The fact that he's running it on IIS through FastCGI seemed to me to be a bigger problem than the fact that he's running WP as well. Not because I don't think IIS is a capable web server, but because Wordpress seems to me to be primarily oriented towards Apache + mod_php. Maybe WP is doing something that's really stupid on IIS + FastCGI but on Apache + mod_php it seems to run fine to me. I just clicked through a poorly visited WP blog of mine while monitoring top and CPU never spiked above 9% use on a 3GHz celeron. (this very same blog until a year ago ran on a celeron 400MHz with no problem as well, btw).

That said, he does have a point that WP's insistence on making everything dynamic is rather silly.
