Thank you. The terminology you use is lost on me but i get the drift. You think the evening losses are OK.
What happened to "Speeds as fast as your line will allow"? My line allows over 11Mbs
Your sync rate is 12.5Mbps but by the time overheads for ATM and PPPoA are factored in you'll get around 2Mbps less than this which will deliver you the 10ish Mbps you say you get.
At the end of the day not every RSP is created equal and in what is now an incredibly low margin industry price can play a factor in performance. If you look at testing results such as Truenet you won't always get the true picture but you'll get a good idea of how various RSP's compare.
