hi , i have 2 squid machine and both of them has the same load of users and BW but of them has 32 G ram and the other has 48 G ram here is a comparision between them : 1-server of 32 G ram squidclient -p 2222 mgr:info | grep 'file des' Maximum number of file descriptors: 65536 Largest file desc currently in use: 52462 Number of file desc currently in use: 39277 Available number of file descriptors: 26258 Reserved number of file descriptors: 100 2-server of 48 G ram squidclient -p 2222 mgr:info | grep 'file des' Maximum number of file descriptors: 65536 Largest file desc currently in use: 52497 Number of file desc currently in use: 50191 Available number of file descriptors: 15345 Reserved number of file descriptors: 100 note that server 1 has larger number of server 2 relative to Number of file desc currently in use , also , i note that server 1 is making better than server 2 in bw saving . my question is , does this relative to ram ??? another issue , how do i know that i need to increase my rams ??? also i want my squid.conf to be checked for any thing could be enhance my server . here is squid.conf file and it is identical to both servers . ========================================================================= here is squid.conf file : include /etc/squid3/vc_squid_3.conf #################################### ############################################################ acl localnetz src 10.11.0.0/16 http_access deny localnetz ################################################################# ###############Redirection of private ips to webpage############# ################################################################# acl localnetx src 10.12.0.0/16 acl localnety dst 192.168.70.2/32 http_access allow localnetx localnety http_access deny localnetx ############filtering without squidguard########### acl blockkeywords dstdomain "/etc/squid3/newsquid-porn.acl" http_access deny blockkeywords ########################################################## acl pornreg dstdom_regex "/etc/squid3/squid-regex.acl" http_access deny pornreg ############################################################ #################################################### #################################################### #acl NO-CACHE-SITES dstdomain "/etc/squid3/not-to-cache-sites.txt" #no_cache deny NO-CACHE-SITES ################################################################ # # Recommended minimum configuration: # acl manager proto cache_object acl localhost src 127.0.0.1/32 ::1 acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1 ################################################################################# # Example rule allowing access from your local networks. # Adapt to list your (internal) IP networks from where browsing # should be allowed acl localnet src 10.0.0.0/8 # RFC1918 possible internal network acl localnet src 172.16.0.0/12 # RFC1918 possible internal network acl localnet src 192.168.0.0/16 # RFC1918 possible internal network acl localnet src fc00::/7 # RFC 4193 local private network range acl localnet src fe80::/10 # RFC 4291 link-local (directly plugged) machines acl mysubnet src 185.6.16.0/22 176.58.64.0/20 188.161.104.0/21 213.244.82.129/32 http_access allow mysubnet ################################################################################### acl SSL_ports port 443 acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 # https acl Safe_ports port 70 # gopher acl Safe_ports port 210 # wais acl Safe_ports port 1025-65535 # unregistered ports acl Safe_ports port 280 # http-mgmt acl Safe_ports port 488 # gss-http acl Safe_ports port 591 # filemaker acl Safe_ports port 777 # multiling http acl CONNECT method CONNECT ###################################################### # # Recommended minimum Access Permission configuration: # # Only allow cachemgr access from localhost http_access allow manager localhost http_access deny manager ################################################ # Deny requests to certain unsafe ports http_access deny !Safe_ports ################################################################### # Deny CONNECT to other than secure SSL ports http_access deny CONNECT !SSL_ports ##################################################################### # We strongly recommend the following be uncommented to protect innocent # web applications running on the proxy server who think the only # one who can access services on "localhost" is a local user #http_access deny to_localhost ################################################################## # # INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS # ################################################################### # Example rule allowing access from your local networks. # Adapt localnet in the ACL section to list your (internal) IP networks # from where browsing should be allowed http_access allow localnet http_access allow localhost ############################################################## # And finally deny all other access to this proxy http_access deny all ########################################################### # Squid normally listens to port 3128 http_port 1xxxxx http_port xxxxxx http_port xxxxx tproxy ########################################################### # We recommend you to use at least the following line. hierarchy_stoplist cgi-bin ?
