Subject: [pve-devel] [PATCH qemu-server 0/6] improve virtio drive multiqueues
Date: Thu, 9 Mar 2023 09:52:11 +0100 [thread overview]
Message-ID: <20230309085217.3649203-1-aderumier@odiso.com> (raw)
Hi,
This patch series add support for virtio-blk num-queues.
It's was already implemented for virtio-scsi.
It's also enable numqueue to maxcpus for qemu 8.0.
Redhat already was enabled by default in rhev in 2011,
so it's pretty stable.
https://bugzilla.redhat.com/show_bug.cgi?id=1827722
It's improve performance for fast storage like nvme,optane
by around 20%.
My fio bench have jump from 200k to 240k iops with 4 block
I don't have seen perf regression (running them for 1month),
but user is still able to override queues and set it to 1.
Alexandre Derumier (6):
add virtio-scsi && virtio-scsi-single tests
virtio-blk: add queues option
cpuconfig: add get_cpu_topology helper
fix #4295 : virtio-(blk|scsi): enable multiqueue by default
drive: allow minimum queues = 1
add virtio-blk|scsi default multiqueue tests
