I'm going off of memory on this one, from posts by Andrew Borts on the
ignite400.org list.  He had (has?) an extremely active site and was
complaining about the expense of upgrading his systems to do the
webserving.  Now this was a few years ago, so maybe the less expensive
boxes have enough horsepower to handle even the most active of sites.

I remember this discussion very well but the problem wasn't so much the
hardware as the HTTP server. The Original HTTP server had some real
scalability issues with CGI (I ran into those myself right before we
switched over) but those have pretty much gone away with the Apache
based server.
