I wonder if anyone else has come across this: When copying all my flacs from Win8 to my Win7, I notice my Win8 computer memory usage spiked to 97% and slowed to a crawl. The Win7 is ok. Both have 16GB of ram.

poolmon.exe shows the tag wfpn is the culprit. Doing a findstr shows that netio.sys is causing the problem. I restarted all the network services but the ram usage is still 97%. Only a reboot will solve this problem.

The Realtek driver is update for Win8. It's consistently reproducible.

I found W8 to be unstable, especially the networking code which takes about 100x longer to connect.

Welcome to W8 is buggy club. :)

Just to check...is it the networking code, or the way the drivers work on Windows 8 for your device?

I ask since one of the things they really focused on was making the network connections come on faster. It's actually one of their huge talking points.

I know on my older machine my connection is always on the instant I bring my machine out of sleep. In Windows 7 slow resume of networks was why I never left sleep on. I just set the monitor to turn off...now I can save power and be ready within about 3 seconds from hitting my spacebar.

Hi sspj,

I have exact the same issue - when copying big files around LAN, torrents,.. Win8 memory usage constantly grows to 3.8GB (total ram is 4GB) and machine starts to crawl. Only restart helps. I used the same technique with poolmon.exe (http://msdn.microsoft.com/en-us/library/windows/hardware/ff560135%28v=vs.85%29.aspx). The problem is with non-paged pool that grows all the time. The driver tag find by poolmon is "Wfpn", findstr finds "netio.sys"... this is the part of Win8 core (MS actually wrote the [bad] code..) :cry:

My machine is HP Pavilion dv7 laptop. With Win7 it worked like a charm..no memory leaks. I'll probably switch back to Win7...Win8 disappointed me.. :s

Anyone knows how to inform MS about that issue?

Might be better to get HP to push out decently coded Win8 drivers, because in all likeliness it will be your driver, not Windows

I've tried two options with updating Realtek Gigabit Ethernet LAN drivers:

1. install Win7 drivers (Win8 still not supported) from HP official support site --> memory leak remains

2. install Win8 Realtek latest drivers --> memory leak remains

I've also disabled LAN interface and tried Wlan only --> still memory leak :(

What else can I do?

really? On my pc im connected before I even log in.

2. install Win8 Realtek latest drivers --> memory leak remains

What else can I do?

Who makes your wireless card? did you do a clean install? what additional drivers did you install? the reason why I ask it might have something to do with something unrelated with the network card driver itself.

I'd agree it's driver related.

I moved a couple of very large ISOs (my dev environment, office etc etc) in a single hit and didn't have any issues whatsoever.

Try running robocopy to move the files and see if the leak persists. It might give you a functioning work around (although it seems unlikely).

I made a fresh Win8 install on HP Pavilion DV7 (not upgrade), it has integrated Realtek gigabit NIC (RTL8168).

After a lot of investigation I think I found the real culprint of my memory leaks. I booted up machine in "safe mode with networking" - and suddenly memory leak has gone :) So I made a list of loaded network drivers (using DriverView from NirSoft) and compared it with the list of drivers in normal boot. Safe mode did not load the following kernel drivers: lltdio.sys, mslldp.sys, Ndu.sys, rspndr.sys, srv.sys, srv2.sys, srvnet.sys, wanarp.sys.

After disabling Ndu.sys (Windows Network Data Usage Monitoring Driver) with Autoruns and normal boot - voila no more memory leaks!!!! :D

Ndu driver was introduced with Win8 (http://batcmd.com/windows/8/services/ndu/) and is actually quite buggy in combination with Realtek NIC. Microsoft should fix that...let's hope soon. :cool:

Hi damkov - you nailed it. Big thanks for you research. I'm surprised that MS hasn't fix this problem yet.

I changed the registry value instead of using Autoruns:

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Ndu

change the Start value to 4 (for disable).

I'm copy over 100GB of data now, memory usage stays at 14%. Normally, it would be 99% by now.

Now I have to wonder "which" Realtek gigabit adapter you actually have.

There are three known versions of the Realtek gigabit adapter - an OEM/semi-generic version (supplied to several OEMs, including nVidia and HP), the RTL8111D/E (also semi-generic, but supplied to several OEMs and IHVs, including ASUS) and the current RTL8111F. (The RTL8111D, E, and F are supported by Windows 8 directly - they all use the same driver, in fact - the earlier version uses a Windows 7-type driver.)

Also, you may want to grab Realtek's own drivers (yes - they actually DO write drivers themselves) as opposed to HP's drivers. (The rather amusing thing about Realtek's driver is that it is a generic, but WHQL-certified, Windows 7/8 driver for the RTL8111D and later - and it works with at least one NVidia LAN controller that I know of; the one included as part of the 630i nForce chipset.)

That issue is not one I've had (RTL8111E PHY), and I didn't have it with the nForce chipset after switching from nForce LAN drivers to Realtek's own drivers with Windows 7. However, if you are used to Intel PHYs and Intel Ethernet drivers (especially gigabit) you may likely be spoiled - I can admit to feeling that way (Intel PRO1000CT was the precedent to in terms of gigabit to the two Realtek PHYs I referred to).

Old thread but seems like a driver issue as was mentioned... I don't get that with my Thinkpad (Intel 82577LM Gigabit) network card.

I'm guessing this should have been solved by HP/Realtek by now. :)

btw good job figuring out where the problem was occurring,but i wouldn't be so quick to blame this on a windows problem. yes you disabled a windows driver to remedy the problem, but it could have been the network card driver not playing nice with the windows driver. seems SHoTTa35 doesn't have that problem,and countless other people with different cards don't have that problem.

    • Sihoo Doro C300 Pro V2 Ergonomic Office Chair review: The Ikea of chairs by Steven Parker I've reviewed a few gaming chairs over the past three years or so and generally found them to score well in our reviews. SIHOO reached out asking if I was interested in taking a look at their flagship chair, the Doro C300 Pro V2. I never got the chance to check out its predecessor, but the V2 is described as an "Adaptive Ergonomic Chair." It became available to buy in April of this year. Let's get things rolling with a closer look at the specifications and features. Specifications Doro C300 Pro V2 Model Ergonomic Materials Mesh Back and Seat; Soft PU Coated Armrests Height adjustability 45.5 - 53 cm / 17.5" - 20.9" Seat (w+d) 52 x 43 - 47 cm / 20.5" x 16.9" - 18.5" (adjustable) Backrest 52 – 60 cm / 20.5" - 23.6" (adjustable) Lumbar support Mesh built-in (adjustable) Armrest adjustability 8D Bionic Armrests Rocking angle 105°, 120°, 135° (fixed) Neck support Mesh built-in (adjustable) Net weight 27.3 kg / 59.64 lbs Weight support 150 kg / 330 lbs Colors Black, White Warranty 5 years (upon registering) Price $499.99, $539.99 Introduction At first glance, it looks like a chair that in another life wants to be a Herman Miller; It certainly looks like my Aeron Remastered, but the Doro C300 Pro V2 has quite a few more features and costs quite a bit less. SIHOO says that it is made up of a "DynaCore" system that tracks your movement and synchronizes the headrest, backrest, lumbar support, and armrests as you shift, twist, or recline. They also say that the "SyncroFlex Backrest" molds to your spine, which kind of describes how the mesh fabric works in most ergonomic chairs, but anyway. Below are the meat and potatoes measurements for the chair. Here is the same tech sheet, but in inches. Durability I would be remiss to not talk about the various durability testing this chair underwent before coming to market, as this is claimed on the product page. First of all, the chair is BIFMA-, SGS-, and TÜV-certified. As for durability, the tests undergone were: 100,000 Castor cycles tested 120,000 Armrest cycles tested 120,000 Recline cycles tested 120,000 Gas lift cycles tested 60,000 Armrest durability cycles tested 120,000 Rotation cycles tested Nothing about weights testing, though. Now that's all disclosed, now onto my own personal findings. Assembly The Doro C300 Pro V2 came in two large boxes (1) (2), and everything was packed very well, protecting the different parts of the chair. In the box, there is a folded sheet that explains the 12 steps to assemble it; they are: Remove the bottom cover on the aluminum base; Insert the five legs into the aluminum base and use ten screws to fasten them; Insert the castors into the legs; Replace the bottom cover on the bottom of the aluminum base; Place the Class 4 Hydraulics gas cylinder into the aluminum base; Screw the bottom part of the arm rests, taking care of the orientation using two screws on each side; Use three torx screws to fasten the footrest to the bottom of the seat; Fasten the backrest to the seat using four torx bolts; Fasten the armrests to the backrest using four Torx bolts (two on each side), taking care to note the orientation; Place the chair onto the Class 4 Hydraulics gas cylinder; Insert the headrest into the top of the backrest; Use two torx screws to fasten the headrest to the backrest. There's also an online guide you can refer to. Carefully unpacking the two boxes took around 15 minutes because almost everything is wrapped in plastic and protective foam; the chair assembly itself took around an hour. I say in the above assembly steps to take note of the orientation, because it's not obvious which way around the bottom portion of the armrests go, and although there is an L and R on the bottom of the armrests, it also wasn't clear from the instructions which was actually left or right, facing the chair, or in the seated down orientation? Anyway, I ended up putting the bottom portions on the wrong sides, and after securing one of the armrests, I discovered that although it was on the correct side, the armrest base could rotate a full 360°, but not when bolted to the chair, so I had to remove it, rotate it, and then bolt it back on. Truly an Ikea experience! Also, to complicate things further, although all the parts are labeled from A to X (yes, that's 24 parts) unhelpfully, these letters do not appear on the parts themselves or the package with the bolts, screws, and washers. There's also a pair of protective gloves in the box, but I think they were made for much smaller hands than I have. Even my friend, who is 5.1, had difficulty putting them on. Once assembled, I needed to sit down. Anyway, as I said, it looks quite similar to my Herman Miller. And here is the back of it. If you look at the product page and on Amazon, it seems like a lot of thought has gone into the chair itself and what it's capable of, but there is no mention at all about the castors, and this is an area where I think the chair trips up quite quickly. I found it difficult to move the chair in any direction. I asked a friend who came to visit me earlier this week to test my findings, and she said that the wheels were "no good," so it definitely isn't just me. I am 6'2 myself and a big guy, I work from home and gained a few pounds from mostly staying in and the hell away from other people. However, the Doro C300 Pro V2 is rated for up to 150kg (330lbs), which in my case is used well within its max rating. Ergonomics The number of adjustments you can make, right up to setting it in nap mode — which I haven't fully tested yet — is what you'd expect from a premium chair. Yes, you can go up and down (max 7.5 cm adjustment), rock back and forth (with tilt adjustment), and lock the chair between three stages of 105°, 120°, 135°, which is not quite as flat as the AndaSeat I tested at 160°. Some thought has also gone into the "8D" armrests, too, which are cushioned but quite firm; you'll only know it if you press hard into the PU-covered tops, which give about half a centimeter, but it's enough to ensure your skin won't get awkwardly stuck to it in warmer (or sweatier) conditions. It almost feels like plastic and is very easy to keep clean. However, the armrest positions move far too easily, and I am not sure what that "elbow" function is. Maybe it is good for a short person with short arms, anyway, I never used it and kept it flat at all times. There are eight levels of adjustment for the armrests, they are: backwards, forwards, swing left/right, height up and down, tilt, and 360° rotation, which can be handy for desk clearance. As I said, the armrest pads shift far too easily, which could give off an ergonomic vibe, but who wants the armrest sliding when you are shifting weight? The height adjustability does lock into place when lifting and adjusting. Comfort This is ultimately what it boils down to at the end of the day, right? Quite a lot of reviews praise the comfort of this chair, and I don't disagree that the mesh seating is quite comfortable. I am used to the material from my daily Herman Miller. However, the backrest cannot be locked into place, and this is actually a feature; as you shift or recline yourself on the chair, the backrest moves with your body. It took some getting used to. The lumbar gives ample support, but I would have preferred an adjustable one built into the seat base, as this causes the backrest to move up and down at will. Again, as with my previous chair review, this chair is also rated for tall people, but nowhere in the product documentation does it say how tall. Being 6'2 myself, I'm happy to say that the backrest is tall and wide enough, and thought has been given to being able to adjust the neck rest, but as others have mentioned in their reviews, people as tall as 6.2ft is about the limit for the neckrest. Conclusion What I didn't like The footrest is rated for 15kg (33 lbs), which to me seems a bit light, and after looking online, it seems like a chair footrest for adults must be at least twice that rating. In all honesty, they are just hollow metal tubes, so it is not recommended to let a kid sit on them. I also feel like it doesn't really go out far enough for my height, so that kind of puts the dampener on me being able to use it regularly. I'll just have to continue to use my subwoofer as a footrest! I do not like the armrests being able to shift around as easily as they can, and they are a little too forward-positioned in the chair to comfortably sit close to my desk, because even in the lowest height position, they don't allow me to go under the desk like is possible with my Herman Miller. I also feel like this chair could have been delivered partially constructed, especially the armrests on the seat, and why the aluminum base wasn't already pre-constructed (without the castors) is baffling, considering it would have fit in one of the two boxes that way. The instructions also need to be clearer. On the pamphlet, there's an A to X listing (which is also used in the steps), but none of the physical parts use this lettering system! What I did like I'll be honest, I haven't used it for very long, just one week, and seating comfort is subjective after all! Any spills wiped straight off it, the stitching, and the lines look great, not a fray to be seen or stitch out of place. It looks kind of cool, too. My favorite feature of these seats is the nap mode. While you're not lying completely flat, it leans far back enough to make you easily doze off after a heavy gaming or working session. Overall, this chair offers plenty of comfort features. The MSRP does vary quite a bit depending on the region, at £549.99 in the UK, and €580 in Europe, and $599 before tax in the U.S. However, shipping is free, which is a bonus for such a heavy item. Is it worth it, though? At three years' warranty, I think it's a decent deal. Another firm out of Germany sent me a free replacement hydraulic gas spring for a chair that failed after almost four years, so it was well outside its two-year warranty. My advice is to always try, as you might have the same luck I did. If I could fault it at all, it would be the constant shifting of the armrests and backrest. Where to buy Although the footrest variant normally costs $539.99, it has been discounted to $469.99 on the official website in Black or White. In fact, the non-footrest variant is only $40 cheaper.

    • The only reason I want to know where you from is because if you are not from the U.K, then why should you care what we in the U.K do or don't do? Racist I am not, I am fed up with the amount coming over here and feel they can come over here and think we need to support them. Do you know how much it costs this country to support these people coming over here? Even when we give them a place to live it is not good enough. We had a barge that was being used to house immigrants, oh but that was not good enough. A mate said to me at the time, when he was homeless, he would have been happy to live on the barge, instead of ending up sleeping on a bench on the beach. I am not scared to say what my family heritage is, unlike you who is scared to say where they are from or where they live. Father side U.S, mother side Wales, still have family living in the U.S. A mate who sadly died a few years ago, had a load of people from different races recording in his studio, I got on with all of them. Skin colour don't bother me, where they are from don't bother me. Religion don't bother me as long as they don't push it onto me and it is not crazy stuff. I am not religious. But if you are not living in the U.K, then why should you care if we are in the E.U or not? This the problem, too many people poking their noses into where it don't belong. But you believe what you believe, if you think I am racist, then be it, I really do not care. Just grow a pair
