Hi, Thank you for this clarification. Can you please tell me what is the best method to measure the RAM used by Squid? Can I trust *top* and/or *ps* and look at the RSS? Or you suggest another method (maybe using the manager)? For instance on a 64x when I start squid without cache_dir and a cache_mem of 0MB, the "*top*" command gives me the following: /PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 10996 root 0 -20 70436 3504 1000 S 0.0 0.2 0:00.00 squid 10999 squid 0 -20 624472 144052 6152 S 0.0 7.0 0:03.34 squid/ But the output of "squidclient -h localhost -p 3128 mgr:info' gives me this: /Resource usage for squid: ... Maximum Resident Size: 576208 KB / Can you please give me advice about that?
