because at the higher data rates (eg 40 gige) it makes a huge difference in host usage. You can fit 6 times in the data in a 9K packet that you can in a 1500 byte packet, which means 1/6th the interrupts, DMA transfers, ACL checks, etc, etc, etc.

This is wrong. Interrupt moderation has been there for quite a while, DMA is chained and predictive.
Just like the extra chopping up of the data you want to send into more packets, it's things you have to do a few extra times. That takes time. There is no way around this. What Leo wrote is in no way wrong.
ACL checks I can agree on, but if you are optimizing the system, what do you need ACL?s for anyway because you can make the applications secure in the first place?
