Subject: Tablebases Too slow what can be improved?

Tablebases are too slow. TB's slow down search to a rediculous point and will
make a 1Ghz machine think it's a P-90.
Is there any work being done to improve function of probing or what can be
changed about tablebases or anything that works with the tablebases to change
this?  I don't have SCSI but i have two drives which are amongst the fastest IDE
drives you can buy 8.2 and 8.9ms access time, you can get SCSI drives that hover
around 4.9ms and up past 10,000 rpm. This i believe would'nt change the Search
hit. This probably has more to do with the first time the TB's are Accessed the
Program continues to Look Even if it didn't find anything to help so at ply's
1-20 Which will come by fast in the endgame are bogged down and now take much
longer.

What exactly is the program looking at and how are the positions stored? I can't
imagine a bunch of EPD's for KPPKPP.
I would think that the compression and how the program looks for the position to
be it's Sore Spot.
