Hi there! My squid is installed on a server with 192 GB of RAM. I have the following directives in squid.conf: cache_mem 143360 MB maximum_object_size_in_memory 300 KB memory_replacement_policy heap GDSF memory_pools on memory_pools_limit 1024 MB ipcache_size 2048 ipcache_low 90 ipcache_high 95 fqdncache_size 2048 top reports that my squid process size is 20GB, which is far less than my RAM size, but nevertheless I still find some page faults (about 70 page faults over 2 hours). I'm wondering how could those page faults are occurring while squid process size is far less than my RAM size. How can I eliminate those time consuming page faults? My second question, am I using correct values for the memory-related directives mentioned above? If no, I would really appreciate if you could suggest the correct values. My last question is about read_ahead_gap, whose default value is only 16 KB. Would increasing this value to let's say 32 KB or 64 KB increase the performance since I have high RAM on the server? Thanks a lot! Regards, Firas
