This seems to be an artifact of Squid's synchronous logging code. (And, in your case, syslog..) It'll probably perform heaps better once I've sorted out this replacement external logfile daemon I wrote a few months ago. The logging performance suddenly allowed people to write > 1000 req a sec to disk. I'll re-read the thread a bit more and see what I can suggest. Adrian
