mostly it is really good, but it is a little slow here and there especially under load, that is where it becomes the most noticeable very quickly, access time tends to get slow and laggy.
benchmarks are a bit degraded from expected speeds, for example my 10TB HGST Enterprise drive seems to get about 40-50% throughput (100-120mb/s at the most where as host can see 220-250) with access times averaging up to 30-70ms inside the VM and both NVME and HDD can end up at 500-600ms response time under load.
NVME is LVM, 10TB is XFS (tried ZFS but it was much slower, used a lot of ram and seemed overkill on a single disk), both set to no cache, IO thread, Async IO: Threads for VM, using VirtIO SCSI controller, only one VM and 2 LXCs running. Guest is windows 10 Pro 22H2 Workstation
i am mostly playing around with AI text/image generation, video editing/conversion, gaming here and there and other fairly demanding things in the main VM so high access time becomes pretty noticeable rather quickly.
any tips, suggestions or thoughts on this would be greatly appreciated. even little things to give a slight boost/edge in any way. (even possibly any cheap hardware i can add)
