Okay, I found the culprit. I updated my Windows 10 VM with all the latest software we use for software development. One of the new tools is Docker (on Windows) using WSL. This made my Windows 10 machine as slow as the Windows 11 one. As I only used it to verify that development in Windows was...

I'm still not happy with the increased latency in Windows 11, so I tried some more fio benchmarking today. Obviously this didn't go smoothly: fio: Windows does not support direct or non-buffered io with the synchronous ioengines. Use the 'windowsaio' ioengine with 'direct=1' and 'iodepth=1'...

Some unexpected progress today. I was pondering the disk benchmarks and my suboptimal disk layout; the 6 disk in raidz2, should have been 3 mirror vdevs (it was a stupider me when I started). So I was thinking about a way to reinstall Proxmox. One of the steps is to upload the virtio driver iso...

Thanks @Dunuin for the elaborate explanation. Really appreciate it. I see I did a lot of things incorrectly in the past experimenting with fio. Lot of re-benchmarking to do. Caching is cool for performance, but a bitch when debugging. Hopefully I have some time this weekend to run the tests you...

Thanks for the fast reply. This is really helpful as I'm still learning all these things. It makes total sense that I'm actually benchmarking RAM as I couldn't really believe these speeds anyway. So I set the cache mode to default (none) and disabled the ARC cache for both VM's. I first ran...

I recently migrated my Windows 10 virtual desktop to Windows 11. However, the system has become very unresponsive and feels really sluggish. There is a lot of delay when clicking or typing. I have scoured the Proxmox forums and Google, but so far I haven't found a solution. I ran some...

Solved my problem by updating /etc/vzdump.conf as described here: https://forum.proxmox.com/threads/can-not-backup-lxc-unprivileged.71878/post-321844 and here: https://www.reddit.com/r/Proxmox/comments/9ucz3o/lxc_unprivileged_backup_task_failing/. My vzdump.conf now looks like this: # vzdump...

I run into the same issue as @neuhausf. A few lines above the error I see another line: INFO: tar: /mnt/pve/nas-nfs/dump/vzdump-lxc-102-2021_11_20-01_00_02.tmp: Cannot open: Permission denied Weird, as other backups do work. I couldn't find a correlation between excluded mountpoints, added...
