Hi, I'm having a server with cache_mem configured to 512MB, and 2 X 25GB of cache. The total memory is 2GB. This server is to cater for 500 users later on. However, my concern now is, with only 20 users using the system, I can see that the memory utilisation has been increasing day by day.(Pls see the table below) Can anybody help me with this problem, because if I cannot find the way to fine tune, then it will be a disaster if I put 500 users??? Or is it a normal situation for squid ? When will it stop to decrease? And for info, I have not startup any other services i.e Apache & cache manager yet to minimise the memory utilisation. top - 16:27:10 up 4 days, 8:12, 1 user, load average: 0.00, 0.00, 0.00 Tasks: 82 total, 1 running, 81 sleeping, 0 stopped, 0 zombie Cpu(s): 0.0% us, 0.1% sy, 0.0% ni, 99.9% id, 0.0% wa, 0.0% hi, 0.0% si Mem: 2075032k total, 1280396k used, 794636k free, 272072k buffers Swap: 4096564k total, 0k used, 4096564k free, 842548k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 2779 squid 15 0 49160 45m 1280 S 0.0 2.3 0:47.06 squid 2782 squid 15 0 2020 268 216 S 0.0 0.0 0:00.35 unlinkd Activity Uptime Squid status % used Total In Used(kb) Total Free(kb) Total Size(2075032 kb) 10/4/06 8:21am 6 min up 0.5 204572 1870460 11:31am 3 hours up 0.7 295236 1779796 5:24pm 9 hours up 1.0 479092 1595940 12/4/06 8:07am 2 days up 1.0 601108 1473924 11:24am 2 days up 1.1 655908 1419124 5:13pm 2 days up 1.4 698908 1376124 13/4/06 8:21am 3 days up 1.5 1137540 937492 2:48pm 3 days up 1.8 1165892 909140 5:11pm 3 days up 1.9 1173764 901268 14/4/06 8:33am 4 days up 1.9 1190452 884580 11:54am 4 days up 2.0 1230908 844124 4:27pm 4 days up 2.3 1280396 794636 Disclaimer Note.
