Subject: Nodes per second........

What is a reasonable number of NPS for a program to search if it has an average
sized evaluation procedure? I.E. what does Crafty get? Chessmaster? Comet? My
program started out searching a very nice number of nodes per second, but as I
added stuff that number decreased dramatically from about 600,000 to 160,000. By
the time I finish the evaluation function (which is currently like 20 lines),
I'm afraid it will be down to like 5,000 NPS on my P233! At what point should I
get worried?
