Hi All, I need your suggestions to improve the performance of our proxy servers setup. we have 4 squid proxy servers running on Open BSD (HP Vectra 600, PIII 700). Below is squid -v output
/opt/squid/sbin/squid -v Squid Cache: Version 2.5.STABLE10 configure options: --prefix=/opt/squid --enable-auth=ntlm,basic --enable-external-acl-helpers=wbinfo_group --localstatedir=/var/squid --enable-snmp We have two 1st tier proxies located on LAN and two 2nd tier proxies located in the DMZ. 1st Tier uses NTLM via the the Samba WINBIND process and 2nd tier with no authentication required. Server A & Server C - 1st tier proxies Server B & Server D - 2nd tier proxies We have been having performance issues for a long time. I have recommended them to buy Sun Fire V240 servers to replace these BSD boxes. But they want to increase memory (from 256 MB to 2GB) on the existing servers and see if that improves the performance. Below is the current cache size on all 4 servers: cache_dir ufs /var/squid/cache 400 16 256 On Server A & Server C we have the following config option on the cache_peer line: cache_peer ServerB parent 3128 3130 weight=15 no-query no-digest cache_peer ServerD parent 3128 3130 weight=10 no-query no-digest After I upgrade the memory I want to increase the cache_dir size to 2GB. Could someone suggest me if I need to change the cache_peer options to improve the performance. I also have cache_mem value set to 64mb at the moment. Do I need to increase that after I upgrade the memory. Any other help to improve the performance would be really appreciated. Thanks.
