Because your cache is busy and using all the memory you gave it for caching objects (cache_mem). This is normal for memory cache, there is no reason to hold it lower than 100% since there is no delay in deleting things when they need to be. > Q1-does that mean that squid dissipated 100% from cache_mem value configured > ????

Is cache_mem set to 1000 MB in on worker? or would that be the sum for all the workers with cache_mem ? > ================================================================== > Q3 > ABOUT snmp with smp > wt i need to configure in squid.conf ?? Squid must be built with --enable-snmp.

It seems not to be harmful particularly, except a waste of effort somewhere. Amos
