This topic seems to be of some interest given the number of views. So here is an update.

Feedback that I received via PM from a moderator is that apparently HughesNet finds the web response times that I reported are not unexpected and that they will be glad to help me try reduce the response time if the response time exceeds 12 seconds.

Maybe it's just me but it seems unusable for many modern applications.  I don't know many folks that would be happy getting a web search result 10 seconds later, or getting a streaming channel change 10 seconds later.  

UPDATE 8/23: Since the web response time does not support my internet devices, HughesNet has kindly agreed to allow me to terminate my agreement early.
