You absolutely do get the increased throughput due to reduced load on the connection, but you can get that by not adding more hardware.
I like the idea of having the validator pull from the upload server(s) whereever they are as that moves hardware instead of adding it, and you can "throttle the link" by controlling the validator(s). Either way, what it does is make the peak load closer to the average load. -- Lynn [email protected] wrote: > You do get some increased throughput if the problem is dropped connections > and packets, and the distributed upload servers have sufficiently better > connections, and the link has to the final upload server has sufficient > bandwidth to handle the load if the connections are carefully controlled > (i.e. pull rather than push).
