Check the c.l.p.m newsgroup for many discussions on threads vs. forks. I'll pull a short answer from one of the discussions: <quote author="Dan Sugalski"> Using fork saves you from programming errors that would nuke your process when running threaded. This is generally a good thing. On the other hand, sharing data between forked processes is significantly more expensive than sharing it between threads, and there are things (such as database connections) that you can't always share between processes. Thread switches are also cheaper than process switches, though that's not a big deal with perl since other factors swamp the (relatively small) task switch penalty. </quote> -- Mark Thomas [EMAIL PROTECTED] Internet Systems Architect User Technology Associates, Inc. $_=q;KvtuyboopuifeyQQfeemyibdlfee;; y.e.s. ;y+B-x+A-w+s; ;y;y; ;;print;; _______________________________________________ Perl-Unix-Users mailing list [EMAIL PROTECTED] To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs
