[ofa-general] SRP aggregate bandwidth decreasing as threads increase

I'm seeing peak performance at ~4 threads (1.6GB/s), w/ threads >10
I'm seeing aggregate performance drop significantly.  This is not a
drive issue: locally, the drives get best performance >~32 threads,
and maintain their aggregate way beyond that.

Is there any tunable parameter or source code change in the initiator
or target code that would effect performance with a high thread count?

Thanks,

Chris
