> Nobody knows about PAUSE frames until they bite you.

I'll be an exception to that rule. I first heard about them when trying to optimize point-to-point 10GbE NIC throughput. I worked with the support team from the NIC manufacturer because I was trying to saturate four ports simultaneously (at the time that was a big deal, it's probably much easier now).

I knew a good deal about them before I was ever "bit" by them.
