[c-nsp] CSM experience under load?

[Steve Francis]

Can anyone share experience of how CSM blades in 6500 deal with load?
Ideally I'd like to know how they handle 25,000 (or higher) 
connections/second (non-SSL) and what their CPU/resource usage at that 
level looks like.
According to cisco specs, it should be negligible, but knowing cisco the 
specs may apply to ideal conditions only (although that problem does not 
seem so bad in general for the 6500 paltform.)
TIA
