--- Comment #15 from rashey@superbox.pl ---
I'm not sure if this is related to PR 253968, but FreeBSD 13.0 have a big i=
ssue
with UFS performance.

You can try to test custom kernel with CAM_IOSCHED_DYNAMIC option to mitiga=
te
the issue.

# Enable dynamic I/O scheduler optimizations
options        CAM_IOSCHED_DYNAMIC
# Publish additional CAM device statics by sysctl
options        CAM_IO_STATS
