Google's HTTP/2 codec slows Envoy

I found it worthwhile and interesting. I'm not in deep with proxies every day and have never had to profile performance like this. The writing was very comprehendable to me and the summing conclusions rounded things out nicely. The first conclusion was probably the most practical takeaway: Codec defaults are performance changes. Its obvious in retrospect but also easy to glaze over when reading release notes.

this reminds that protocol compliance and performance aren't always aligned

Im not entirely sure what the motivation was for replacing nghttp2 with oghttp2 - nghttp2 is probably the most used codec for http/2 - so probably not compliance. I think it was mostly about code reuse since oghttp2 is part of QUICHE which is also used in Envoy for QUIC.

This is a company blog. I run some paragraphs through ai to fix my dogshit sentence structure since english is not my first language (come to think of it, my russian has always been pretty lame too). Get over it
