Re: [squid-users] squidclient mgr:info

Hi Yomi,

ICP & HTCP are protocols used between 2 or more cache servers to
communicate and share their data , if you only have one single cache
server then you don't have to worry about ICP or HTCP.

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.
