Congratulations on the 3.2 release! It seems quite stable in our >1000 client environment, good work! Some first impressions after using it for some days (Linux x64, no disk cache, SMP mode with 2 workers): On an old server (SLES 10) the load sharing between workers (2 or 4) is pretty bad, in fact only one worker seems to do all the work. On a SLES 11 system load sharing is a lot more fair. But as you stated is this OS related, not a direct Squid issue. The shared memory cache is harder to follow in its memory use than in 3.1, am I right that the "cached" value of the "free" output is somehow related due to shared mem? And some kind of little bug maybe related to SMP: If I rotate the logs (1x access.log and 1x cache.log) they spread both to log.0/.1/.2 and suddently access.log.0/access.log.1 and cache.log/cache.log.0 are used in parallel. However, 3.2 with SMP seems to be a really nice scalability feature. Thank you! Daniel
