Title: Re: PAIX Well... remember it's speed of light THROUGH fiber which isnt the
same, its actually a bit slower then "c"
Coast to coast you should see 35 - 65ms depending on the
route.
We've all had this thread about router overhead. If there
is a congestions point in the middle with buffering and traffic level
priorities running, then you are right. Otherwise I dont think
you should see 150-180ms.
In the real world however, yes, off several dsl links Im seeing
those levels to various sites, I think it's more a factor of congested
peering links or traffic aggregation at a hub. People arent
spending the money to upgrade links right now.

light. Add equipment, especially routers or other gear that requires
manipulating packets and the delays add up quickly. I once read that
the most people wil tolerate on a regular basis is around 150-180 ms.
I think that is much too high for regular use
