I'm running 12.2 and 13.0 on KVM using virtio and zfs. I am not having
disk I/O issues.

Hello List,
I hope some other folks out there running FreeBSD on KVM as well. I set up a
base VM while doing so I noticed that the disk operations are very slow. Many
times I edit a file in vim or try to run a command there is a huge lag.
I use UFS as the root filesystem. To have something to compare it with I have
tested it against an OpenBSD 6.6 VM on the same host, same hardware. both have
1 vCPU and 1GB of ram, 20GB virtual disk (they are exactly on the same physical
disk no raid or anything to have a fair comparison).
Here is an example simple file search time for a non-existent file:
FreeBSD 13
time find / -name cacert.pem
real 0m30.656s
user 0m0.516s
sys 0m3.938s
Second run even worse
real 2m38.618s
user 0m0.711s
sys 0m6.882s
While on the OpenBSD VM I get
time find / -name cacert.pem
real 0m2.258s
user 0m0.290s
sys 0m1.970s
The amount of data is about the same on both systems but I would not consider this a
"slight" performance degradation. If the base system is so slow then imagine
putting Apache and other servers on top of it. Did anyone run into this?
Unless there is a definitive solution I will opt out to using other BSD
variants.
