GP meant 5 orders of magnitude below "20 ms". 20 ms is a lot of time.

There is nothing one can do to a, say, a 1 kilo byte buffer that will cross 1 ms in any language. My own Go code doesn't cross more than few micros per message.

GP's root claim is that protobuf serialization/deserialization performance shouldn't matter, on an article where a user is specifically demonstrating that it does matter.

The usecase described in the article, and the usecase described in the top post in this thread aren't the same usecase. If you aren't throughput bound, a 5% regression in parse speed doesn't matter if your goal is to stay under 20ms and parsing takes 17 us. Sure it now takes 19 us, which is a regression of 2 us out of 20ms, or 1/10000th of your time.
