My guess would be file system speed.  The benchmark should be done
with logging on a different spindle than the data, and both file
systems having the "soft updates" feature turned on.  Linux' file
system is essentially the equivalent of BSD's "async" option, but the
soft updates accomplishes the same thing in a much safer manner.

Also, the threads implementation is a big factor.  Running under
BSD/OS 4.x, the speed improvement is quite good using a faster file
system.
