I have a problem with my wordpress site, it was just too slow. It was taking me 20-30 seconds to load the page, initially I thought it was nearlyfreespeech, and was contemplating moving the blog to dreamhost (both of whom happen to be amazing webhost by the way).
The reason I thought it was a host problem because my browser kept displaying ‘waiting for keithrozario.nfshost.com’ while the waiting, so I assumed that it was their servers response time. That however was too presumptuous on my part, and it took me a while to get to the bottom of things, but I finally figured it out.
I used a nifty little Firefox plugin called firebug.
