Hi, I'm trying to optimize speed by using mod_deflate on a particular personal server. It runs Apache httpd 2.052+ and PHP Version 5.1.6, with eaccellerator, on Linux 2.6.9-023stab033.6 SMP kernel for CentOS 4.5.
Roughly, it serves 5 websites, combined they get about 1 real human visit each second in total (excluding redirected hits, blocked spammers/IPs/robots/spiders). One of the sites is behind SSL, for squirrelmail webmail. Most filetypes it serves are php (flatfile non-mysql weblogs), a few text and .htm* files, a very small cgi-script here and there (and a couple of imagefiles, avi's and mp3's, but not very much). Bandwidth/traffic are no problem factors for this server, it runs with a 100 mbit NIC to the net, and I can use it wide-open. Currently it uses about 210 MB of DDR3, and I have at least another 128 MB of RAM left, and CPU also has room to do more.
From the current httpd.conf :
# added gzip for mod_deflate: #<Location /> SetOutputFilter DEFLATE BrowserMatch ^Mozilla/4 gzip-only-text/html BrowserMatch ^Mozilla/4\.0[678] no-gzip BrowserMatch \bMSIE !no-gzip !gzip-only-text/html SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png|wav|mp3|ogg|bmp|avi|mpg)$ no-gzip dont-vary Header append Vary User-Agent env=!dont-vary DeflateCompressionLevel 5 DeflateMemLevel 9 DeflateWindowSize 14 #</Location> #AddOutputFilterByType DEFLATE text/html text/plain text/xml (When I uncomment the Location tags, Apache won't start. Haven't figured out why, but doesn't seem to matter, since I'm running it for all the sites anyway.) This httpd.conf has had a pretty long life, so I forgot much of what I've changed over the years. But I was wondering how I could better load speeds for php webpages using mod_deflate, and also, handy pointers on how to best measure this perhaps, although I don't have very much time to spend on that. I just wonder if any of you sees really strange or bad general config values. For that I'm posting some other more or less crucial values from the same conf: Timeout 120 KeepAlive On MaxKeepAliveRequests 60 KeepAliveTimeout 22 # SendBufferSize 16384 <IfModule prefork.c> StartServers 8 MinSpareServers 4 MaxSpareServers 16 ServerLimit 256 MaxClients 256 MaxRequestsPerChild 800 </IfModule> <IfModule worker.c> StartServers 4 MaxClients 128 MinSpareThreads 16 MaxSpareThreads 70 ThreadsPerChild 24 MaxRequestsPerChild 800 </IfModule> LoadModule access_module modules/mod_access.so LoadModule auth_module modules/mod_auth.so LoadModule auth_anon_module modules/mod_auth_anon.so LoadModule auth_dbm_module modules/mod_auth_dbm.so LoadModule auth_digest_module modules/mod_auth_digest.so LoadModule ldap_module modules/mod_ldap.so #LoadModule auth_ldap_module modules/mod_auth_ldap.so #LoadModule include_module modules/mod_include.so LoadModule log_config_module modules/mod_log_config.so LoadModule env_module modules/mod_env.so LoadModule mime_magic_module modules/mod_mime_magic.so #LoadModule cern_meta_module modules/mod_cern_meta.so LoadModule expires_module modules/mod_expires.so LoadModule deflate_module modules/mod_deflate.so LoadModule headers_module modules/mod_headers.so #LoadModule usertrack_module modules/mod_usertrack.so LoadModule setenvif_module modules/mod_setenvif.so LoadModule mime_module modules/mod_mime.so #LoadModule dav_module modules/mod_dav.so #LoadModule status_module modules/mod_status.so LoadModule autoindex_module modules/mod_autoindex.so LoadModule asis_module modules/mod_asis.so #LoadModule info_module modules/mod_info.so #LoadModule dav_fs_module modules/mod_dav_fs.so LoadModule vhost_alias_module modules/mod_vhost_alias.so LoadModule negotiation_module modules/mod_negotiation.so LoadModule dir_module modules/mod_dir.so LoadModule imap_module modules/mod_imap.so LoadModule actions_module modules/mod_actions.so LoadModule speling_module modules/mod_speling.so CheckSpelling on #LoadModule userdir_module modules/mod_userdir.so LoadModule alias_module modules/mod_alias.so LoadModule rewrite_module modules/mod_rewrite.so LoadModule cache_module modules/mod_cache.so LoadModule suexec_module modules/mod_suexec.so LoadModule disk_cache_module modules/mod_disk_cache.so LoadModule file_cache_module modules/mod_file_cache.so LoadModule mem_cache_module modules/mod_mem_cache.so LoadModule cgi_module modules/mod_cgi.so # added april 2007: LoadFile /usr/lib/libxml2.so LoadModule unique_id_module modules/mod_unique_id.so LoadModule security2_module modules/mod_security2.so #LoadModule evasive20_module modules/mod_evasive20.so Those last ones I'm still experimenting with. For now I use mod_security with only very basic defaults. This server doesn't really suffer from DDoS attacks often. Any advice or improvements highly appreciated.
