Web Hosting Speed Issues…

Web Hosting Speed Issues…: "About  three weeks ago I became obsessed with finding out every major inefficiency with our code, with Cpanel, and with Linux itself (The OS we run our hosting company on)."

This is in a post from Matt Heaton, president of BlueHost, the hosting service I use for NearWalden and some other domains. There's a gzillion hosting providers out there. Why did I end up with BlueHost? a) their prices were competitive, b) they had an extensive online forum, and c) their president had a blog. So far they've been great, and based on what I've seen they'll be willing to tell me when they haven't been great, which is what I'm looking for.
