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.
