Plug POST performance

Oh, we definitely tested with the right URL, sorry, just a bad paste of one of the many we tried (we were just testing fallback vs actually correct route at that time).

I’ll play around with the phoenix code (we actually tried, at one point, a new phoenix app modified to just 204, same results) as well as HiPE to see what that does. I played around with eflame for profiling but all it really showed me was most of the time was spent in cowboy/ranch. I did a couple of graphs by "grep -v"ing out the cowboy code and very little was left.

I’d be curious and surprised if you saw the same results using the “Ebid” code I had in the gist, as it shouldn’t really pay any attention to the body contents. From what I can see by reading plug code that only kicks in if you are actually using one of the parsers, and that code doesn’t parse anything.
