Hi,

 I'm also curious about this "waste of time" as well, and I often leave my
computer downloading overnight, so I guess I wouldn't mind giving you some
figures.
 I'm not that happy about running this "DistributedPerftClient.zip" in my
computer, though.
 The ratio logarithm of depth to time is roughly linear, at least up to depth 8,
so if you give me a FEN position, and a reasonable depth to calculate , I could
come back to you with a figure in about 24 hours.
 I estimate that I need at least 2 hours for a perft 8... and maybe much more as
the game develops (a perft 9 wouldn't let me use my computer for days). I have
an Athlon 1800+, and I use Movei because it is quite fast for perfts. If you
know a faster one, let me know, because otherwise the "four" computers that you
have used for your figure are about 4 or 5 times faster than mine!!!
 Regards,

  Jaime
