This is a silly test IMNSHO, but if you really want to it you should
also try compiling it on a UFS file system with softupdates.
Additionaly, unless you are using native FreeBSD binaries instead of
Linux binaries for the compiler, etc, the comparison isn't fair because
there is some cost associated with making many syscalls, especialy
open(2) which may result in extra reads.
