That does sound a bit poor.  I presume the system was basically unloaded
during the buildworld.

Can we see the output of:
- vmstat -i
- zpool status -v
- df -k
- mount -v
- md5 -t   [this will help determine if the problem is lack of CPU]
- sysctl vm

How did you test them and what were the results?

Do you know what revision your
/usr/src/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/arc.c is?
(Or when/how did you last upgrade your source tree).
