Windows 2022 Laggy (Terminal server and SQL server )

[TheSover]

I am going to try to integrate the zvol in a new server, I have tried to buy an identical server and install ESXI and the performance is excellent as we had before in the same hypervisor(ESXI), but we wanted to change to proxmox for the management level, it gives you a thousand more tools and it makes our work much easier,backup server is amazing!

But we need a good performance... apart from implementing zvol, can you think of what else we can do?

What tell us simply windows task manager of the guest: cpu, disk, memory, network utilization - what does it look ? Guest are busy ? What about network? No problems, packets lost etc ?

For my Windows 2019 VMs I've practically set everything as defaults including KVM64. IDE with default settings. Keep in mind I am using ZFS so alot of the speed enhancements are handled by that. You can clone your VM to test out some settings.

Have you tried your Windows VM's with Host CPU type and VirtIO SCSI Single controller? I think youll find better performance with that.

I work with VirtIo SCSI Single Controller and i've tried Host CPU too

No, the guest is not busy

I make an installation in another provider (OVH) with the template of OVH that sets all Space disc on local and they used (local) for everything doesnt separe isos, templates, from backups and VMDISK the machines works perfect, I think the key is on the installation of de OS I will find the diferences post it if i find what is diferent . We are close!

is zfs too ?

 

[TheSover]

No, it's not zfs

 

[_gabriel]

ZFS vs non-ZFS isn't comparable if hardware differ.
As many topic & docs says : ZFS require enterprise grade disks, as DataCenter SSD with PLP protection.

 

[TheSover]

Finaly it was ZFS and the disk because it was a low quality SSD's
