This post discusses how to reduce the amount of memory they use without killing performance. The caveat, of course, is that you’re not going to be able to run a site with a large database and large amount of traffic with these settings. I’m going to try to explain the WHY more than the WHAT. All of this is in conjunction with my goal of reducing the amount of ram I use on my Xen based virtual server, as discussed previously in, Low Memory Computing. Before I begin, I’d like to say that you should also look at various system utilities that consume ram. Services like FTP and SMTP can and should be passed off to xinetd. Also, you should look at shells besides bash, such as dash. And, if you’re really serious about low memory, you might look at using something like BusyBox, which brings you into the realm of real embedded systems. Personally, I just want to get as much as I can out of a standard linux distribution. If I need more horsepower, I want to be able to move to bigger, faster virtual machines and/or dedicated servers. For now, optimizing a small virtual machine will do. First off, Apache. My first statement is, if you can avoid it, try to. Lighttpd and thttpd are both very good no frills webservers, and you can run lighttpd with PHP. Even if you’re running a high volume site, you can seriously gain some performance by passing off static content (images and javascript files, usually) to a lightweight, super-fast HTTPd server such as Lighttpd.
