repo-templates VS grpc_bench

I lead the Microsoft Open Source Programs Office team. I'm sorry this happened.

We have merged a pull request that restored the correct LICENSE file and copyright, and are in touch with the upstream author Leśny Rumcajs who emailed us this morning. We'll look to revert the entire commit that our bot made, too, since it updated the README with a boilerplate getting started guide.

The bug was caused by a bot that was designed to commit template files in new repositories. It's code that I wrote to try to prevent other problems we have had with releasing projects in the past. It's not supposed to run on forks.

I'm going to make sure that we sit down and audit all of our forked repositories and revert similar changes to any other projects.

We have a lot of process around forking, and have had to put controls in place to make sure that people are aware of that guidance. Starting a few years ago, we even "lock" forks to enforce our process. We prefer that people fork projects into their individual GitHub accounts, instead of our organization, to encourage that they participate with the upstream project. In this situation, a team got approval to fork the repository, but hasn't yet gotten started.

To be as open as I can, I'd like to point out:

- The templates we apply on new repositories live at https://github.com/microsoft/repo-templates

SayHello, GetUser, and Sum differ only by payload size. Sum is the simplest one - (int, int) -> int, GetUser is (long) -> User (medium payload), and SayHello uses exactly the same payload as this test: https://github.com/LesnyRumcajs/grpc_bench/tree/master/dotnet_grpc_bench

This is correct. The problem is not with the benchmark itself but with the implementation. If you look at the result, you can see that even with 6 "allowed" CPUs, the vertx server utilizes less than 100%. Apparently, the current vertx implementation (the one implemented in https://github.com/LesnyRumcajs/grpc_bench/tree/master/java_vertx_grpc_bench) is single-threaded or has some other limitation.

Another iteration of grpc_bench!

Because it's fast and runs on Windows, Linux, and MacOS

In general though, akka/pekko-streams are known to be one of the fastest implementations out there. Their grpc client for example even beats languages like Rust (see https://www.lightbend.com/blog/akka-grpc-update-delivers-1200-percent-performance-improvement and https://github.com/LesnyRumcajs/grpc_bench/wiki/2022-03-15-bench-results).

The whole point I was making is at least up until 8 months ago (at best, I can't commend on the stability/maturity/performance of shardcake) Akka was the only mature library/ecosystem solving this problem with also a very strong focus on performance (for example still to this day, akka/pekko-grpc is generally one of the fastest grpc implementations I am aware of, its even beating rust if you have at least 2 cores (see https://github.com/LesnyRumcajs/grpc_bench/wiki/2022-03-15-bench-results)

It would be interesting to create a new java benchmark with your implementation.

Also worth checking out the gRPC benchmarks: https://github.com/LesnyRumcajs/grpc_bench/discussions/284

dotnet is up there with Rust.
