Thanks Michael, I guess my question was a little misrepresented. Just to clarify for others; I don't need certain streams to be lower latency, just the overall latency of the internet connection seems off. I would love a more concrete measurement than seat-of-my-pants feeling, I'm just not sure what the best method to measure such things are.
To respond to your comment, we are using our own internal caching DNS servers, which are themselves redirected to opendns which is allegedly the fastest DNS service available. Besides that, what makes me think it is unrelated to DNS is that even intra-page content is relatively slow. So even though the HTML may have a delay in loading, if it was DNS the images and other resources should load quickly, which isn't the case.
