I don't know why that happens, but I wouldn't expect it to give you much of a performance boost, since IDE doesn't do asynchronous I/O (at least under *BSD anyway). If you have a very busy system, I would expect it to give you a performance drop, in fact. ----------------------------------------------------------------------------- Michael L.
