Ohh, now I see what you are trying to tell me. Just install sql server on linux and manage it under Windows pretending it's installed on windows :D That might actually work. Thanks lad. :cool:

:D I am coming from gentoo, I am trying this for someone else and he insists on MS SQL.

windows 2019 result ur fio settings thread8,iodepth=8 write: IOPS=44.6k, BW=174MiB/s thread1, iodepth=32 IOPS=9,8k, bw=38.4MiB/s <= ????? thread1,iodepth=1 write : IOPS=IOPS=7249, bw=28.3MiB/s

First of all, thank you very much for your response. I think it was RAID10 ZFS HBA Mode. Tried ZFS RAID10 through HBA Mode and RAID10 on Hardware Controller, then ZFS0 and ext4 on proxmox. I tried both. On proxmox host I get full zfs10 raid performance and on windows vm guest I get about...

Hi wolfgang, thank you for your response. I agree with your points and I am sorry if I posted something too quickly and hastily. The bottom line is, that the 4K IO performance is very low e.g. (30mb/s instead of 90mb/s). Well I am still trying to test 5 trillion other things including what...

Exactly, but just as the thread mentions, the issue persists inside the vm too. After trying 5 trillion things, I assume there is some issue in the IO path like you mentioned but I just cant figure it out. 8x Samsung PM883 in DELL PERC H730p mini HBA mode under RAID10 ZFS in proxmox are...

hmm, from what I have been reading, it is exactly same issue I have. I am also passing disk through HBA mode.

Hey wolfgang, thank you for your response. I am talking about the low IO performance under ZFS RAID1 or RAID10 :( I would like to refer to my thread https://forum.proxmox.com/threads/pveperf-disk-performance-slower-than-standard-raid.59570/

I have the exact same issue here. Can someone clear up on whats going on?

any ideas? :D

First of all, thank you for the quick response. I still do not know why I am getting such low numbers :confused: Here are some recent fio benchmarks:

Hey, I tried almost everything out there to get this working, I have major issues to get proxmox up to speed: 8x PM883 Samsung SSDs in H730p RAID10 on bare Windows Server 2016 Installation = 5GB/s reads (e.g) good speeds in general same as above on bare proxmox Installation = 1GB/s under...

Hi guys, I am currently trying to get youtube playback to run smoothly on my Windows-VMs but I am having an major issue here: - qxl, spice vdagent installed - qemu guest agent installed - all latest drivers are installed (latest virtio, tried also stable) still, youtube playback is stuttering...

Ich schließe mich der Fragen an. Bitte um Hilfe. Wir sind schon zu Zweit :):eek:
