Software compile isn't a that good benchmark. There can be differences in
compiler, make, system includes or something else that could affect
build time. It's not clear at all that the time difference comes from
filesystem operations.
I hope that at last this is on identical machines (including disk and disk
controller:)

You should try to compile your software using linux binaries and includes
under a NetBSD (for example, copies a linux install in /emul/linux,
'chroot /emul/linux /bin/csh' and build your software).
