Lot's of sql queries is a culprit.
Bad programming practices is another, with the code showing squared
But the biggest problem is without a doubt a lack of caching.
A subproblem here is that the sites are designed without caching
considderations in mind.
A Pentium 133 can easily fill up a 10Mbit line. That is a lot of requests.
So if you have a system that can generate static pages, that Apache can
serve you can have really fast systems.
