Speed Problems (random read/write) with Proxmox vs. Vmware

[starlight]

Hello,

i build up a testing rig... there is one NVME with proxmox and one with VMware... the random read/write in proxmox VMs are not as good as in VMware ... first i thought this is a zfs problem, but the speeds are nearly the same with ext4.

the cache is turned off, i tried vmdk,raw and qcow2 , no difference. all virtio drivers are up to date

is there any solution on this ? the random speed is only around 50% of vmware speed.

This is not usual. What is your VM configuration?
Please adjust your VMID if necessary:

cat /etc/pve/qemu-server/100.conf
