We are looking at adding an additional ISP to the mix and we are thinking of purchasing an Ethernet circuit from Comcast in an attempt to increase performance on those connections by keeping all the traffic within Comcast's network. Comcast, of course, has assured us this will result in "noticeable" speed increases for those accounts. I am more weary. Does anyone have any experience with Comcast's ethernet offerings? How reliable are they? Do Comcast cable connections see a significant performance improvement?

It will only help if the performance issues are related to the Comcast
Internet peering connections, otherwise you'll see no difference if the
issues are related to congestion occurring on the coax connections from
the optical nodes that services each coax feed through neighborhoods and
business. This is simple over-utilization that (at least in our neck of
the woods) is becoming more and more a problem as Comcast saturates
there networks with too many connections...there is only so much
bandwidth a coax line can handle! I suspect your performance issues are
related to the latter.
