I run http://knitfreedom.com, and am hosting it through GoDaddy shared hosting. The downtimes and huge slowdowns I’ve experienced over the past month have driven me insane.
I’m about to switch to a Drupal site, but that’s a few months out.
I’m looking to switch my hosting to Site5 dedicated server hosting, but I have a feeling that the host is only half the problem.
I don’t know if my W3 Total Cache is set up properly, but SOMETHING is causing a 20 second load time.
I had a quick look at your test and the first thing I would look at is that your page weight is nearly 2.5Mb. This is mainly due to the size of some of your images. Sort those out and I think you will see a big improvement.
