Tested the website I am working on and saw that the first page takes extremely long time to load. This happens with other pages on the website but not the home page.
Your first request is without a trailing slash and Apache serves you a 301 redirect to http://www.nylesa.net/about/ (IIS does the same thing too.)
This is irritating at all times but very illuminating here. The second request is quick enough (and it is this one which returns the actual html.) So the standard Apache bit is slow, but ‘your’ page is fast.
This is certainly something that you should raise with them. I’m scratching my head for any suggestion as to what it might be; you’ll have to make sure that this gets to their tier 3 support.
