thanks a lot Mark.
sorry i made a mistake just now, the correct report for the squid process
should be as follow, the one i posted just now is for runcache process. for
squid process, it seems that VSZ is not significantly larger than RSS.
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
nobody 19729 48.9 32.4 1303636 1301388 ? S Apr03 10682:44 squid -NsY
the return from top is
top - 15:06:17 up 23 days, 10:18, 4 users, load average: 1.20, 1.13, 1.06
Tasks: 66 total, 2 running, 64 sleeping, 0 stopped, 0 zombie

7563 root 12 0 956 956 760 R 5.6 0.0 0:00.06 top
according to the results, is there any problem with the memory status? sorry
for so many questions..thanks a lot.

The total process size is reported under the column VSZ; which in
your case is 2276.
The part in memory is reported under the column RSS, which is 1056.
This means you have a problem; total memory avail. can only handle half of
SQUID code, which will make the squid process swapping, hence it
will become slow.
You need more physical memory.
