I tested your site speed at http://www.bytecheck.com/

It took 9.5 seconds for the first byte to load (this about 7:40 a.m. EST)

When checking my own site, if slow, I also run the speed test on some random other sites I visit. If everyone slow then I suspect my server. If only me slow, then I suspect either me or host. To rule myself out as culprit I run site through something like www.webhostinghero.com/ www.webpagetest.org
