Hi Everybody, I have a question regarding memory usage for squid. I have 4 proxies, each has about 200-400 req/s and 2-5 MB/s with ntlm_auth and about 1000 lines of acl, squid version is 3.0.STABLE15 on Redhat AS 5 Linux. They are busy servers and therefore have no disk cache but memory cache of 6144 MB (6 GB) and provide the internet access for some 10k users. That is the reason we use no disk cache: Disk cache resulted in huge iowaits and poor performance even though the servers are HP ProLiant DL380 G5 with a RAID controller that had 256 or 512 MB of read/write caching. Performance was poor even with caches distributed on different disks. The squid process needed about 7.5 to 7.8 GB and that seems reasonable. After we enabled ICAP (c_icap with clamav virus scanning) the memory usage of the squid process rose to about 12.8 GB. Is this a normal behaviour with squid when icap is enabled? Following is the icap configuration part in squid.conf: +++++++++++++++++ icap_enable on icap_preview_enable on icap_preview_size 128 icap_service service_avi respmod_precache 0 icap://localhost:1344/srv_clamav icap_class class_antivirus service_avi icap_access class_antivirus allow all ++++++++++++++++++ I enabled ICAP only for resonse, not for the requests up to now, therefore there is no reqmod entry The old configuration was with parent proxy (where the virus scanning took place before), now the squids send the requests directly to internet (no parent proxy).
