I think I also just came up against the same effect that the original poster
saw. I have two sets of machines here - one is a pair of dual core Xeons,
the other a pair of quad core Xeons. They are HP servers, more or less
identical apart from the processors I belive.

Both have 7.0-BETA3 installed, and the same config on them with the
same files.  I am trying to delete a gigabyte of files using 'rm -rf'

On the dual core processors this takes about 20 seconds. On the quad
cores it takes about 3 minutes! This is true for both the 32 and 64 bit
versions of FreeBSD :-(
