Typical CRUD API server is going to do quite a few allocations, maybe use the "default" (underwhelming) gRPC implementation to call third-parties and query a DB (not to mention way worse state of ORMs in Go). It's an old topic.

Go tends to perform better at "leaner" microservices, but if you are judging this only by comparing it to the state of Java many years ago, ignoring numerous alternative stacks, it's going to be a completely unproductive way to look at the situation. Let's not move the goalposts.
