Why is a lower load important to you? Depending on the script you could introduce a "sleep 1" between each compression step, which gives the system I/O a chance to catch up. Obviously you could also vary the "1" as needed. -- Carl Fink [EMAIL PROTECTED] Read my blog at nitpickingblog.blogspot.com. Reviews! Observations!
