Good day, Can someone assist me on how to reduce my cache misses, configure my page faults and RAM for squid best performance. See below for summary of my cache activities. Regards, Yomi. "from you squidclient info I can see some bad things like your cache miss time : Cache Misses: 51.56862 which is extremely high. Another thing is the Page faults with physical i/o: 25098 , the lower this number , the better performance you get...this indicates that you are using too much RAM and your process is using swap partition and decreasing performance."
