The overhead you're seeing with execs is best avoidable by using a better infrastructure. I'm sorry if you'd have to recode things, but to be honest the speed rates are something like this (worst to best): - pass and exec - pass_persist - embedded perl - C -- Wes Hardaker Cobham Analytic Solutions ------------------------------------------------------------------------------ The NEW KODAK i700 Series Scanners deliver under ANY circumstances!
