Here's a tip I recently discovered: don't use GoDaddy for your PHP/MySQL projects! Their servers are stupidly slow when executing PHP/MySQL scripts. I discovered this on a recent Drupal project where I was using some JSON services. The total time for the http request on my local development server was less than a second. On GoDaddy's server the exact same http request was taking anywhere from 8 seconds to 30 seconds!

To verify GoDaddy's slow servers was actually the problem, I installed the site on my Lunarpages webhost. The same request took a bit longer than my local server (which is to be expected), but it consistently came in around 1 second.

It's amazing to me that GoDaddy could be so successful while offering such poor service. The majority of their clients must be using static websites (cached and static pages loaded up decently quick for me). Nevertheless, I recommend avoiding them, especially for your PHP/MySQL projects.
