WP sites will run extremely slow if you have either GoDaddy or Network Solutions as your hosting. I speak from experience. I’m not a big fan of those 2 companies’ shared hosting service. They’re fine if you want to register your domain but get you shared hosting somewhere else. Any other place have much better shared hosting. And if they try to have you buy a dedicated server… don’t fall for it. No body need that just to run a blog.
Also try “PHP Speedy” plug-in to help speed up your site (Just Google it). Use “WP Super Cache” plug-in. And don’t forget to delete unnecessary plug-ins. Optimize your database as well.
