I would like to just point out, the actual bottlekneck is not the framework which many frameworks and blogs tend to put on their cover photo, but the logic, database, 3rd party APIs or other micro services. Please do look into them before optimising your framework aggressively, even if you use a framework written in Godslang and your database can answer only 5 Req/sec its no use.
As a young developer I was there, and now I speak of experience that framework Benchmarks dont workout in real world as expected. New comers beware.
