Greg,

Performance is not my area of expertise but you
said any input is helpful... so here it goes:

If your network has been the bottleneck in the
performance then your proposed upgrade should
increase your performance.  Will it be
increased by 10x?  I doubt it. Once you remove
one bottleneck, the next ones shows up.
(Disk, CPU, TSM Server resources, etc.)

TDP for Domino does have a multi-processed,
multi-buffered engine that will attempt to
keep feeding data to the network as quickly
as possible. In addition, you could run
multiple instances of TDP for Domino to
get even more parallelism and utilize
more network bandwidth.

Thanks,

Del
