I started optimising the Squid-2 codebase to remove a lot of the CPU hogs but its a big job and noone seemed willing to sponsor any work. Try out the Squid-2-HEAD codetree and see if you notice any difference. There's plenty of work that can be done to Squid-2 to really cut back on the CPU overheads but *shrug* noone showed enough interest. Adrian
