Actually I'd say the opposite.  It's not real world because the conditions are 
_harsher_ than real world.  It's really difficult to generate 64 streams of 
data from a single client, and they did it.  As to it being harder on the 
server to receive from a single client vs receiving from multiple clients, I'm 
not sure if that's the case.  64 streams from one client or 64 clients -- it's 
still 64 streams that have to be multiplexed (or not) on the server.

This email is to be read subject to the disclaimer below.

Its not real world because it doesnt represent the typical backup scenario 
of having many clients all writing to the one server. There are big 
overheads in multiplexing all that data into a single stream...

Cheers,
Matt

It's only back to back because they're waiting on their new switch.  Why 
isn't it real world?  Just because they don't have a switch in between?

Curtis, 

may not be a lie, but not exactly real world either!

Back to back?

Still, as you say, an impressive result
