Speed Test?

[Synth]

My site only has 38 members and of those there are really only 1-3 people on at a time, including guests. Yet when I go to my site it generally takes about 5-8 seconds just to load the front page. I have a few hacks installed but nothing I would think could slow it down that much. If you could go to my site and tell me what you think www.theholonet.net. I am on a shared hosting plan, but would that make a huge difference? I know it would if there are alot of sites sharing but this is bad. It even takes long just to follow a link from my navbar and back home. Is it my site, my style, my hacks, my hosting? Also is there a way to check the speed at which it is loading and compare to something that will give me a better idea at how fast it should be loading?

Any help or comments are greatly appreciated
