That's really bad... I know Rasmus is very interested in getting rid of System Calls :) He discovered that they do a lot of damage on performance, I don't know how far he is or what changes he has made. For what I've read, performance *has* dropped since 4.1.2 (or 4.2.3), would be nice if that could be improved :) -- Tom Sommer, Denmark www.dreamcoder.dk - www.tsn.dk
