Be aware of the equation number of hosts * max thread-pool size * number of CPUs = potential DB sessions. Too many connections all trying to read and write to your MessageBox at the same time can overwhelm SQL Server, locking up the system and reducing your throughput dramatically.  According to research I found, you should try setting the max threads per cpu down to (say) 50 and see how that affects your processing.  You can check the following link for instructions on how to do this:
