Subject: Slow EGTBs

I do more or less the same thing as everybody else, when probing EGTB's, judging
from the open source programs I've inspected. But I get a severe drop in NPS
when the tables are probed heavily. Much more than other programs, from what I
can see on ICC.

What could be the course of this?
I have the same order of number of probes as other programs as I can see on ICC.
So my limiting of probes is not the problem. I only probe in the first couple of
plys and if there have just been a change of material on the board. The harddisk
I use is very fast. It is a Western Digital 80GB 7200 RPM with 8MB cache. So
that shouldn't be the problem either. I use NTFS, not FAT, I don't know if that
makes a difference, or file systems in general. I haven't done any serious
testing of this on EXT2, EXT3, ReiserFS etc. But as far as I know, people are
able to do this on Windows, so I must be able to do it too.

If you have any ideas on how to test or narrow down what's wrong, please post.
