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.
