Abysmal (broken, really) Windows 10 guest disk read/write performance

User Support
1

Hello.

I’m having some performance issues in a Windows 10 guest with QWT 4.1.67 from here. The behavior is very distinct, which is why I’m hopeful that someone here will immediately know what’s up

EDIT: Qubes R4.2.3 up2date

A copy of a folder from one disk to another, or from one disk to another directory on the same disk starts off (relatively) fast, ~200MB/sec then after ~10 seconds, it drops dramatically, until it’s at 1-2MB/sec

The guest has 32GB RAM (fixed, no ballooning) and 4 cores

The first thing I thought was write-caching but I have it disabled for the disk in Windows

I would say the issue is dom0 since it’s doing the backend IO, but I have no issues with the QEMU disks or NVME passthrough disks on Linux guests. The resources in dom0 are plentyful, 32GBRAM, 8 dedicated cores

FWIW, I’m seeing the same behavior with an NVME passthrough disk in the same guest…

Here’s the logs from the guest

I’m hoping this is some known issue with QWT/Xen that is specific to Windows guests rather than something larger …

2

Is there a reason you are using 4.1.67 instead of 4.1.69? Is the behaviour the same using 4.1.69?

3

There is no specific reason I’m using 4.1.67 rather than 4.1.69, aside from it was the one that I was able to find and/or was referred to while building this (some time ago now)

Is there a reasonably trustworthy build of 4.1.69 available somewhere that you’re aware of? I would like to not have to build an environment to build QWT just for an airgapped VM that won’t have anything sensitive on it if possible

Thank you for your response by the way, it would be wonderful if 4.1.69 resolves whatever this issue is (though I’m not too hopeful)

If I can’t work it out I’m considering trying Win8.1. I noticed Win7 doesn’t have this issue, but it’s more difficult than I expected getting software that runs on Win7…

4

OK, I’m sorry, I see now, sudo qubes-dom0-update qubes-windows-tools-4.1.69 - at the time I used qubes-windows-tools, which gives you the empty ISO (just a README saying ‘not safe, build it yourself or download from a random stranger’ …) so I ended up using the release referenced by the qvm-create-windows-qube project, which apparently points to 4.1.67

Will give 4.1.69 a shot and pray :slight_smile:

5

Well, 4.1.69 copies a little faster for the 5-10 seconds that it copies, but same issue unfortunately - drops to 0 and doesn’t move from there

I see at qubes-issues on Github that the development for support beyond Windows 7 is actively continuing, so maybe this is expected for now

I’ll give WIndows 8 a shot, not necessarily expecting success, but easier to try that quickly than digging any further into the root cause

6

Good luck, I haven’t tested the speeds on my windows vms, I just figured there might have been some changes between 4.1.67 and 4.1.69 that helped in that regard.

That is unfortunate, I’ve been keeping an eye on the latest development, I haven’t got it to build yet, so I havent tested it either.

This seems hopeful - Windows support in Qubes - #29 by hackerfactor

I was wondering why Device Manager was showing unknown devices, even after running the QWT installer. Maybe the drivers just need to be copied manually after the QWT installation?

I’ll give it a try as Windows 8.1 downloads to my third-world Internet …

Xen Network and Disk PV drivers are not installed by default, you need to specifically select them in the QWT installer to be installed:

Thanks. I gave it a try yesterday but didn’t have successful results

I had this working at one point on another Windows 10 appVM, it required a bunch of booting to safe mode (probably my own fault) but I can’t seem to get it out of a loop where it completely hangs at boot or blue screens. That appVM was created from a Win7 Ultimate, then a really bizarre (seemed like almost a glitch) way of both upgrading to Win10 + activating. Some key intended for special IoT VMs. Because it’s really, really hard finding a legitimate key to buy, and because the various standard ways for updating work on everything except LTSC Ultimate

Back to the point from my traumatized bitching :slight_smile:

For now I’m going to ignore the disk issue since the application I use can run fully out of ram, and the input files are only 300MB max, I don’t think they’ll trigger the issue

I’m looking forward to the outcome of the current development, I was convinced it was effectively dead when I first saw the GitHub issue 3-5 months ago or so, but now there are pretty recent updates and a bunch of items appear “done”

Thanks both of you for the notes. I realize now I was under-informed when I posted, and honestly even if there were some ideas about specific steps to troubleshoot/resolve, I didn’t have the time priority-wise to participate

I am curious, though, if anyone else is not seeing this behavior. Just control-c, control-v a directory with a couple of GB of data inside

We’ll see if anyone chimes in here over the next few months. I don’t think there are a ton of users actually using Windows, let alone Windows 8 and above. I guess the gamer crowd, but I always assumed that was a very small group. And they may not do large sustained file read/write, just lots of small/medium reads and the occasional write

Cheers

I did get the PV disk driver working eventually, after many reboots and hangs. It did not resolve the performance issue - and it actually made things worse - processes in the VM crash spuriously, occasionally the kernel crashes (BSOD) and occasionally the VM window just goes poof

I’m wondering if this is related to this issue or if it’s just a coincidence… I am seeing the errors in dmesg. I don’t understand BTRFS implementation well enough to know if those errors actually impact logic or if they’re purely warnings. If they’re purely warnings rather than errors communicated back to the process performing the i/o operation, then I guess it’s just (un)lucky timing :slight_smile:

(I need to stop mixing the two accounts I have, q1w2e3 == Churros)

I think I see now why I was using that specific build - when using qvm-create-windows-vm, which automates the installation via an answers file and some scripts, the MSI must have certain options set as the default, otherwise you need to make modifications to the qvm-create-windows-vm scripts otherwise the post-install steps don’t execute. Mystery solved :slight_smile:
