A lot of things go into it, most of it is kernel performance at
various tasks like context switching, process creation/teardown,
memory allocation, filesystem / cache / I/O scheduling...all areas
where Haiku is comparatively young and not yet very performance tuned,
hence the speed difference. BFS can slow it down somewhat as well,
since file creation / deletion by necessity also involves updating
whatever indices those files belong to, which doesn't occur on other
OSes. That's not enough to account for anything close to a 5 fold
performance difference on its own though.
