Perhaps Steven has a bug and is trying to open >these non-existant files on each probe... I had the same problem some months ago. I don't remember, if it was a 2x slowdown, but it was very significant. If I remember it right, the disk light was not flashing then, but I may be wrong here. Since then, I've always been running WCrafty with the egtb=0 commandline option. Heiko.
