[squid-users] Page faults

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."
