I'm just wondering what's wrong with FreeBSD 8.0/amd64 when I read the

And yeah, quite honestly: disk scheduling in FreeBSD appears to suck... The
only reason I'm not switching from Linux. :(

Hello Thomas.
I recall myself having had similar problems during heavy disk I/O (UFS
and ZFS) with stuck console, stuck clients and especially stuck
X11-clients. The discussion was really 'hot', but in the end no clear
statement was made whether this is disk-i/o related or a deeper problem
in the scheduler.
Sorry for the lack of the link, I thought Phoronix is well known ...
