AT&T MPLS / BIB Routers

[Mikeal Clark <mikeal.clark () gmail com>]

We just put in a AT&T MPLS and are having a pretty negative experience with
the "Business in a Box" routers they are using for our smaller sites.  We
are seeing extremely high latency under load.  Anyone have any experience
with these devices that could shed some light on this?  Are they really this
bad?
