I've been assured that the line performs close to a LAN connection.

don't believe that until you see hard round-trip-time numbers.  LAN latencies 
are under
a single milisecond (unless badly configured), but even short WANs are hard 
pressed to
go under 10msec.
It clearly depends on distance.  The hard limit here is speed of light.  So the 
best theoretical latency between, say, New York and L.A. is 30ms round-trip.  
In practice, if you're seeing double that (60ms), you're doing well, since the 
fiber isn't a straight line and each hop adds a little latency of its own.


mmm, a bit off there - it's way bigger, roughly the same amount of inhabitants.

Anyway, we're small.
