Upload speeds are slow until computer is restarted


Recommended Posts

I am having a strange problem..for some reason when I go to upload something to say like mega, 1fichier, solidfiles, etc..pretty much any file host site my upload speeds only go to like 200 kb/sec but when I restart my computer and try again, my upload speed is maxed out, and regular speeds like I'm suppose to get, and I get 75 MB up..so usually its like 7.8 mb/sec and its fine for like a few hours, but then it does the same thing until I restart my computer. And when I run a speed test, that comes back fine (see below) so I don't know what is going on here. Can anyone help? and also my connection is hard wired

I just ran another speed test at the same I was trying to upload something like you said, still getting around 200 kb/sec and speed tests are fine. and I checked in my router, there is no traffic shaping or traffic priority going on.

"75 MB up..so usually its like 7.8 mb/sec "

Well since you reversed Byte and bit here with your Big B's for bit and little b's for byte.. so are you seeing 200KByte or Kbits up because its a huge difference..

what I would like to see is a sniff when its real low and then a sniff when its working as normal.. Grab wireshark and do that.. you don't need to run it for the whole upload..  But run it for say 30 seconds on your slow upload and then 10 or so seconds on FAST upload.  PM me if you have any question on using wireshark its free and just sniff and then save the file and they might be large on your good speed upload..  But I can give you a place to upload them too so I can get them, etc.

Next time vs rebooting your computer just disable your interface and re enable it.  Are you wired or wireless?  With those speeds and that 4ms ping time I would for sure say wired, but want to make sure.  The speeds are doable with for sure with decent wireless but the ping time is really low for a wireless connection.

I'm wired directly to the router/modem. What do you want me to do exactly with wireshark? just let it run for 30 seconds with my good speed uploads, then again with the slow speed uploads?

I just tried what you said Budman..disabling it and re-enabling it(didn't know you could do that to fix a connection) and my upload speed was normal again when trying to upload something(see video I took below). Now I just gotta wait, because it's random when the upload speed at 200 kb/sec happens, so I'll post that second video when I try it again in a few hours

I doubt that has anything to do with it.. But you find them in the advanced section of the driver.  Different nics, different drivers will have different options you can play with..  But I doubt its a setting like that you could tweak that is causing you a problem.

Offload is normally something you want ON!!  If your nic supports it, if doesn't and you have it on it just wouldn't do anything and still work.  What OS are you running btw?

so has it happened again, have you taken any sniffs?  Does it happen on small files as well - what size of files are you sending.  If not too large you can just do the full sniff.  But if like 100MB then yeah the sniff would be 100MB in size ;)  Really curious to see the sniff when its bad!!

Yea it is still happening, but it is good to know that I can just disable and re-enable my network card without having to restart my computer to fix it(thanks BudMan). But it happens on files of all sizes, anywhere from 10 mb to 500 mb it's really strange. The next time it happens I will open up Wireshark and what should I look for..anything going to the file hosting site? which is solidfiles.com ?

also my network card is a Realtek® 8111E

and the network card drivers are up to date

Yeah like to see the transfer.. are you getting really all delays in the acks, is the window size not ramping up?  Are you having to retrans, etc. etc..

Kind of need to see a trace when your rocking full speed vs one when its ######.  Just because you restart your nic doesn't mean its really your end..  Maybe your sending to a different IP when its slow vs fast, etc.

 

grabbing now - but have to head to work in like 30 seconds.  Will look at today.

They are big most likely because you were downloading big files ;) 

edit:

Ok took a quick look, hope to get some more time later today.  But yeah your slow speeds make sense from the sniffs and your window size.  As you will see in the slow upload your largest size was 17462, less bytes on the wire in that frame..  While in your fast upload 62834 bytes in the frame.

Notice that in your fast upload you windows scaling is working scaled your window size by 4..  But in your slow upload scaling factor is -1?? I think this is because I missed the syn,ack for the start of this conversation so wireshark doesn't know what the scaling factor is suppose to be so just guesses.. (seeproblemwindowsizepic)  But clearly they are not the same.. So something not working in figuring out the scaling factor for the upload.  When you move large amounts of data over a wan you want a large window so you send more data in less number of packets.  So less back and forth acks while moving large amount of data.  In your slow upload your largest size is that 17k while in your fast upload your sending almost 63K bytes worth of data each time.

Now your sniffs are with 2 different file sizes or atleast showing that so not sure if you were sending the same file and just cut off the sniff or what haven't look that deep yet.  But in general if your window size is small to send say 10MB you need X number of conversations back and forth.. While each should take about the same time lets call it 30ms for example.. So if you can send that same 10MB in less interactions of send and ack, you can move that 10MB faster..

Clearly in your fast upload your sending more data per conversation then when your slow sending - huge difference between 17k and 63k.  So need to figure out why something is not working out right in your scaling?

What does this output for you?

C:\>netsh int tcp show global
Querying active state...

TCP Global Parameters
----------------------------------------------
Receive-Side Scaling State          : enabled
Chimney Offload State               : automatic
NetDMA State                        : enabled

Receive Window Auto-Tuning Level    : normal
Add-On Congestion Control Provider  : ctcp
ECN Capability                      : enabled
RFC 1323 Timestamps                 : disabled

Can you grab a sniff from the start of your sending so I can see the syn.ack and then wireshark should be able to correctly figure out the window size for the conversation.

Thanks for looking over the files BudMan, really appreciate it.

I did the first command line like you asked and this is what came back

And also here is the sniff file you asked for. I started sniffing before I even had the website up, then I tried uploading the file while it was sniffing, and these are my good speeds again, because like I said those slow upload speeds I get when attempting to upload happens at random times.. https://www.dropbox.com/s/6156l4s1cna46wo/fast-upload2.pcapng?dl=0

The good speed sniff had the syn,ack part.. What I would like to see bad speed with the syn,ack of the upload stream..

You might want to try turning these on

Add-On Congestion Control Provider  : ctcp
ECN Capability                      : enabled

netsh int tcp set global congestionprovider=ctcp

This can ramp up your window size quicker and could help in speed.  Can't hurt to turn it on.. And then do you upload tests, if you don't continue to see your good speeds or better than set it back to none.

edit: ok took a look at that next sniff and as you can see good window size sending large packets.. While your bad one was only sending 17K at the LARGEST...

I ran that command(as administrator) and it changed, then tried and it started out fast but then was transferring at about 2.1 MB/sec but then I closed out the site, stopped the sniff and tried again and my speeds were maxing out(you can take a look at the sniff file if you want, just let me know). But ok, I will try again some time later tonight or whenever, because like I said the slow speed is always at a random time, and I'm not uploading all the time, only when ever I feel like it, so the slow upload speeds can happen when ever..even at peak hours aka prime time 7 pm to 10/11 pm.

So if your uploading and your window size is small, then yes it will be slower if your window size is larger..  Without seeing the syn,ack of the conversation starting its impossible to see what and why they might not work out a large window size.

Ok you caught the syn so you see no windows scaling. This is why your slower is your sending smaller frames.. Remember before where you were sending 63k here your sending 17k  HUGE different for speed over a wan connection.

Now just need to figure out WHY??  Let me look deeper and do some research on why windows scaling would not be used.  Did you change the option?  Also I don't like that yours has that * on it about windows scaling an heurstics - from my understanding what is reported is not always what is used..  I have to run out early this morning..  Will have more info later.

 

you enable ecn with from an elevated prompt.

C:\>netsh interface tcp set global ecncapability=enabled
Ok.

Can you show your globals again, are you still seeing the ** The above autotuninglevel setting is the result of Windows Scaling heuristics

So can you do this command

C:\>netsh interface tcp show heuristics
TCP Window Scaling heuristics Parameters
----------------------------------------------
Window Scaling heuristics         : disabled
Qualifying Destination Threshold  : 3
Profile type unknown              : normal
Profile type public               : normal
Profile type private              : normal
Profile type domain               : normal

Notice I have mine disabled..

Here you go BudMan

c:\>netsh interface tcp show heuristics
TCP Window Scaling heuristics Parameters
----------------------------------------------
Window Scaling heuristics         : enabled
Qualifying Destination Threshold  : 3
Profile type unknown              : normal

    • Microsoft 365 Roadmap Weekly: Compact notifications in Teams, improvements to Copilot & more by David Uzondu It is the end of another week, which means there's a new batch of additions to the public Microsoft 365 Roadmap. Most of the additions this week were focused on the usual Microsoft products like Copilot, Edge, Teams, and Outlook. Let's start with Edge, because a change is coming to how the browser handles links from other apps, with an expected arrival in August. If you use different Edge profiles for work and personal stuff, you know the drill. Right now, your setting for a default profile takes priority. When this Edge update rolls out, an application like Teams or Outlook can recommend a profile, and Edge will prioritize that recommendation instead. An admin policy called "EdgeOpenExternalLinksWithAppSpecifiedProfile" will be available for organizations that want to control this behavior. Microsoft Teams is getting a few tweaks aimed at improving day-to-day use, spread out across this summer. Arriving next month, notifications are getting a compact mode, which shrinks them down for a more minimalist look on your screen. The ability to save messages and posts is also on the way for August. Teams will also get noise suppression for people who dial into meetings with a phone. It will automatically filter out background sounds like traffic or keyboard clatter, making calls clearer for everyone involved. This is set to roll out in September. If you spend too much time digging through old emails, an update for Outlook planned for next month should help. A new "Browse Conversation Files" feature will gather every file shared within an email thread into a single, easy-to-access view at the top of the conversation. Moving on to Copilot, the AI assistant will get one-click buttons to instantly generate FAQ or briefing pages from content in your Copilot Notebook. For managers, a new "scoped access" feature for the Copilot Dashboard will let them see adoption and usage stats just for their specific teams. Microsoft is also bringing the basic Copilot chat to its Department of Defense (DoD) customers next month, with web access turned off by default to "meet US Government requirements."
    • AMD power plans are not a thing anymore. That was their poor man's attempt to influence scheduling in Windows until they got Microsoft to update the scheduler to better understand the concepts of CCDs, which are super important to getting the correct performance form Ryzen. I never really understood how a power plan could have that effect, but I do know they are no longer needed.
