I concur -- gzip is a beast on the IO, this is most likely where your perceived lag is. Install the "sysstat" RPM on your machine (and make sure it's started) and let the 'sa' processes gather data for you. Then, use iostat and 'sar -P ALL' to examine the relative IO alongside the CPU usage and you'll have a much clearer picture. It's possible you're running out of ram during the gzip (hey, who knows!) and are hitting your swap, which could be a killer. -te -- Troy Engel | Systems Engineer Fluid, Inc | http://www.fluid.com
