It is unlikely that somebody will guess what your bottleneck is just by reading the above description. I recommend that you start by looking at CPU cores and Squid processes in top(1) when Squid appears to be slow and answer the following initial questions: 1) Are there any CPU cores approaching 0% idle? 2) Are there any Squid processes approaching 100% CPU utilization? 3) Are there any Squid processes in D (blocked) state? 4) Is total free RAM below 10% of total RAM capacity? You may want to post representative top snapshots here, accompanying your answers to the above questions. Again, this needs to be done when your Squid is unhappy (at least). Make sure you configure top to show Squid process names (press 'c' in many top implementations) and individual CPU cores (press '1' in many top implementations). HTH, Alex.
