Hi everyone, The COSS code in Squid-2.6 has come quite far from its original design by Eric Stern. Steven Wilton has put an enormous amount of effort into the COSS design to fix the remaining bugs and dramatically improve its performance. I've assembled a quick webpage showing the drop in CPU usage and the negligible effect on hit-rate. Steven Wilton provided the statistics from two Squid caches he administers. You can find it here - http://www.squid-cache.org/~adrian/coss/. Steven is running a recent snapshot of squid-2.6. The latest -STABLE release of Squid-2.6 doesn't incorporate all of the COSS bugfixes (and there's at least one really nasty bug!) so if you're interested in trying COSS out please grab the latest Squid-2.6 snapshot from the website. Adrian
