sysctl -a |grep dirhash
Check vfs.ufs.dirhash_mem is not close to vfs.ufs.dirhash_maxmem if it is
and only most used boxes this seems to be the case increase maxmem.
Seems this could either do with an auto tune option or a larger max by
default in today's day and age.

Have you checked that your dir hash isn't suffering due to lack of memory
this can have a marked impact on seemingly trivial things like this as
could silly things like the RAID card being installed in a different slot.
RAID card is onboard on these things - how would I check the dir hash ? The
slower server has 16 gig of RAM, the faster one has 4 gig. Both were
installed the same way in the same order, so should have the same disc layout
more or less.
