GitHub user akrasnov-drv added a comment to the discussion: VM Disk performance issue
Hello @NuxRo, Thank you for your reply. I hoped to get some other answer, e.g. that I missed some way to do the desired changes. Till now we used own VMs with dedicated disks and pinned cores (core pass-through with no reuse grouped per numa). These VMs accomplish our tasks significantly faster than CloudStack VMs with the same resources. For now I don't think the difference could rise just because of CPU cores (I also configured cpu pass-through, though without numa optimization), so only the disks are left. I'll try to experiment with this more. For now I believe the problem is in layered disks. If anybody gets ideas on optimize disks in CloudStack, please share. Thanks, Alex.
