datapoints on 10G throughput with TCP ?

I see significant difference between number of interrupts on the Intel and the AMD blades. When performing a test between the Intel and AMD blades, the Intel blade generates 20,000-35,000 interrupts, while the AMD blade generates under 1,000 interrupts.

There is no longer throttling, but the performance does not improve.. 

I set it via 

sysctl hw.intr_storm_threshold=0

Should this go to /boot/loader.conf instead.
