I am using OpenBSD 3.4 with Apache compiled with mod_perl, and have 768MB of RAM. I am using an IDE hard drive. I have enabled soft updates, which improves disk performance, but that's about it. I still would like to find a way to generate the graphs every 5 minutes instead of on the fly with 14all. I hope that someone can tell me how to do that.
