Humm strange for XP to be doing that oddly, maybe faulty ESXi vmxnet3 drivers?

Got a server 2003 SP2 here (not on a N40L but a HP proliant) and it runs full speed if I push files to it or pull files from it using windows and linux clients.

Really? What are the disks involved here? That is some SCREAMING performance!! Are they SSD? Or do you have a different controller added or just the native controller?

So what is your VM to VM peformance?

Well maybe not all that screaming, depending I guess -- just did a test from my storage vm to my physical machine.. And seeing real close to what you got

C:\test>robocopy \\storage\media\cleanup c:\test test.mp4

And didn't realize it until I made a change about offload in the nic driver on my storage vm for testing that my son was streaming a moving at the time of that test ;)

Nothing but amazed at the performance you get get out of such a cheap little box... The OP clearly has something really jacked up.

something really is screwed up with mine.

I performed another iperf test between 2 XP VMs last night and was getting around 400MBits/s

I am tempted to do a reinstallation of ESXi and the VMs and see if there was anywhere i went wrong.

I am currently booting ESXi from a USB drive and storing the VMs on the 250GB drive which came with the N40L. Am wondering if other guys have a similar setup with these boxes?

To RAW Map them you need Dedicated Storage for that Disk IN the virtual machine. Can you do that. You shouldn't need to with your set up. Sorry I meant how are they formatted as in Thin Provisioned or Thick Provisioned etc.

the XP and WHS vm are both thick provisioned

Its a normal 2TB SATA. My physical PC is SSD.

I am using the 250GB that came with it as my datastore, I really did not see the point of installing esxi to usb to save a few gig of space on the 250GB drive that esxi requires. Depending on your setup usb might make sense, say for example your host did not have any local storage.

So your running embedded version of esxi vs installable version? If you were going to setup a raid array for your datastore - sure use usb to boot esxi so that its not installed on your array, etc.

But sounds like your wanting to do what I am doing.. Using a VM as a NAS/Storage/File server - which you have added disks to use as space for this VM. So raw should be an option for you just like in my case. These other disks are not going to be used by another other VMS - they are just storage drives. The 250 is my datastore drive - this is where all VMs OSes get installed - and to be honest 250GB is a quite a bit of space for just VMs that are just test/play boxes and not serving up data. For example my pfsense has a 8GB drive assigned to it on the datastore, and that is over kill ;) My linux shell box also has 8GB, again overkill for what it does. w7 I gave 40, again overkill and setup as thin anyway -- if your going to be storing data on your storage Vms other drives.. 250GB is quite a bit of space ;)

Did not see the reason to save a couple of gig by installing to a USB. But it really shouldn't matter which way you go from a performance point of view of esxi, other than maybe bootup time. I would have to hope mine boots up faster than yours off sata installed hdd vs your usb ;)

I've got ESXi installed on USB, wasn't aware you could install it on the storage hard drive, all the documentation I read at the time (mostly Dell stuff) said you NEEDED to install ESXi itself on a USB because otherwise you couldn't use the drives for storage if you installed it on them (USB gets formatted fully as FAT32 whereas ESXi storage volumes are VMFS3 or 4 or 5)

yes thats more or less what i want to do, have several VMs for test/play boxes. I want a datastore to stream movies to my XMBC - hope to use WHS2011 for that.

      The problem isn't with Epic, it's with the platform holders like Steam and Nintendo, they should be a lot more strict in their review process.

    • Microsoft updates Visual Studio Code with easier language model discovery and in-app search

      By zikalify · Posted

      Microsoft updates Visual Studio Code with easier language model discovery and in-app search by Paul Hill Microsoft has released Visual Studio Code 1.125, its latest weekly release. This week, the company has focused on discovering and installing extra language models via the Marketplace; searching the web and securely browsing over remote connections without leaving VS Code; choosing how long VS Code waits before installing extension updates; and delivering managed Copilot settings through existing device management tooling. In older versions of VS Code, extensions could contribute their own model providers, but to find these extensions, you needed the right tags to search for in the Extension view. Now, the Language Models editor gives you an Install Model Providers button that opens the Extensions view, which is filtered to extensions that contribute model providers, making it easier to find and install them. Once you install a provider, its model will appear in the model picker. If you use the integrated browser much, you can now look up information without leaving VS Code by typing a query into the integrated browser’s address bar. It will use your configured search engine, the same way a standalone browser does. You can use workbench.browser.searchEngine to pick a search engine. When the browser is opened in a remote workspace, it's now possible to proxy HTTP(S) traffic via the remote connection. This allows you to connect to any ports or services that can only be accessed from the remote machine. If you read our coverage from two weeks ago about VS Code 1.123, you might have seen that extension updates have a two-hour delay as a safety measure. In this update, Microsoft is giving you the ability to configure the time of the delay. You can find it under extensions.autoUpdateDelay. Finally, with this update, admins can deliver managed GitHub Copilot settings through native device management (MDM) channels on Windows and macOS, in addition to account-based enterprise settings files. Settings delivered via MDM appear as policy-enforced in VS Code and can’t be overridden locally. Future updates will extend the supported policy keys across Copilot surfaces. You can download the update from the Visual Studio Code website now.
