This is pretty bad since we are allocating for every single enqueue now. I will raise one or more follow up PRs to reduce this significantly. I was able to remove all allocations except one in the runtime.
# Motivation We want to benchmark our `NIOAsyncChannel` to see how it compares to the synchronous implementation with `ChannelHandler`s # Modification This PR adds a new `TCPEchoAsyncChannel` benchmark that mimics the `TCPEcho` benchmark but uses our new async bridges. Since Swift Concurrency, is normally using a global executor this benchmark would have quite high variation. To reduce this variant I introduced code to hook the global executor and set an `EventLoop` as the executor. In the future, if we get task executors we can change the code to us them instead. # Result New baseline benchmarks for the `NIOAsyncChannel`.

Should we just grab the next() from the shared singleton?

nit: naming threw me for a sec as I expected a buffer, not a ByteBuffer. something like messageSize is a more obvious

Thanks for the review. Going to address them in my next PR that I am going to open in a few minutes. |
