James, On my last Internet proxy, I've almost the same config(no cache) as Your proxy. I added this line to my conf: offline_mode on And commented out those unuseful lines: acl QUERY urlpath_regex cgi-bin \? no_cache deny QUERY The cpu load lowered by 10%. Ciao, Graziano ELSAG SSC Direzione Servizi Continuativi Graziano Sommariva ICT Network Manager * +39-10-658.3921 * +39-348-8558742 * Graziano.Sommariva@xxxxxxxx -----Original Message----- From: James Vanns [mailto:jimv@xxxxxxxxxxxxxxxx] Sent: mercoledì 16 novembre 2005 12.22 To: squid-users@xxxxxxxxxxxxxxx Cc: Paul Mills (paulm@xxxxxxxxxxxxxxxx); Benjamin Tanner Subject: CPU saturation? A question to the floor. We are running squid 2.5STABLE3 and have a non-caching setup including the following configuration statements: <snip> cache_dir null /dev/null acl all src 0.0.0.0/0.0.0.0 no_cache deny all ident_lookup_access deny all request_timeout 1 minute connect_timeout 1 minute fqdncache_size 2048 pipeline_prefetch on half_closed_clients off client_persistent_connections off server_persistent_connections off </snip> With approximately 3000 open file descriptors (configured at compile time and set at runtime with ulimit -HSn 16384) and an equivalent no. of client/server TCP connections we see a constant CPU usage of ~95-100%. Is this normal!? The hardware is as follows: Dual Intel(R) Xeon(TM) CPU 3.20GHz (Linux of course manages the CPU affinity as we know squid isn't multi-threaded) 6G of memory Disk stats shouldn't matter as we aren't caching. If this is not normal do we need to upgrade to patch a known bug that I have failed to find amongst all the squid resources on the NET? Any help would be appreciated.
