I trust you have checked cache.log, system log, and network interface statistics for warnings, errors, and red flags unique to the non-working use case. Make sure that browser-proxy path is about the same in all tests you compare. The problem might be related to browser-Squid communication. Since you have a "working" case (on "smaller hardware"), I would try the following using identical Squid versions: 1. Use the default Squid configuration with Squid memory caching disabled on both boxes. Is one setup still a lot "slower" than the other? 2. Compare access.logs and mgr:info output of the two tests (one test performed after a clean Squid start). Any unexpected differences? 3. If you have not already, test a Squid configuration identical to that "working" case (you can rename directories/hostnames if really needed, of course, but do not change anything you do not have to change). Is one setup still a lot "slower" than the other? 4. Comparing cache.logs of virtually identically configured Squids with debug_options set to ALL,3 or higher may expose the critical difference. Debugging will slow Squid down a lot, of course, but perhaps you will see that one of the Squids is doing something that the other one does not do.
