Comment (by trevorwekel):

 I agree with Bruce. The limit of 62 concurrent connections for the
 ACE_WFMO_Reactor will be too small to fully load upcoming multi-core CPUs.
 The select reactor limit is somwhere near 1000 connections.  I believe a
 3:1 ratio of connections to cores may be required to adequately load the
 !MapGuide Server under certain conditions.

 AMD is scheduled to release 24 cores on a 2 socket machine sometime in Q1
 2010 and Intel also has larger core counts in the works.  Assuming a 3:1
 ratio, 72 connections will be required to load a 24 core machine.
