I don't believe having a single submit machine is a Good Thing - it's going to be overloaded with startd processes (one for every job submitted), so it's  bound to be the bottleneck of your pool.

Minor nitpick but since this list is archived and searching it is
useful it should be noted that the submit machine would be overloaded
by _shadow_ processes.
Also the major reason (at least for now) for the overload is less
likely to be the shadows (except on windows where they hit some hard
resource limits near the 200 mark) and more likely to be that the
schedd cannot keep up due to its largely single threaded approach*

* though 6.8 adds quite a bit more non blocking IO and the negotiation
overhead should be significantly reduced from 6.6 levels in the common
case.
