note neilwatson I would followup with this warning. When determining the maximun number of forked processes, please test carefully. The ideal situation is to test on a non critcal machine. Start with a small number and work up. Monitor performance closely. <p> Using the Parallel ForkManager can greatly increase the speed of your scripts. However, without proper testing it can bring a machine to its knees. I speak from experience. <p> Neil Watson<br> <a href="http://watson-wilson.ca">watson-wilson.ca</a> 291446 291446
