Implementing a fast path when there's no constrained label should limit a lot the number of allocations.

Closes #1276

Nice, thanks for this!

I think it makes sense, but we need to clean up those benchmarks. They are mostly duplicate and will get obsolete very soon. So either we use b.Run or remove them for now.

BTW Were those useful? Did you gather some info? Or just helped you to finalized the implementation? (:

They essentially helped me to see the progress and if there were some remaining optimisations that could be done.

Great 💪🏽

I feel we can either drop those benchmark for now if you don't have time to clean them or create one or two with table tests so others can run it on their PRs to verify if there is any regression 🤗

Sorry for the delay, I got busy at work and couldn't find the time before :) I rewrote the benchmarks as a table test, it should be easier to maintain like this 👍

Any chance we cut get a release that includes this fix?

We have some tests that our metrics collection doesn't allocate in go-libp2p, and we currently can't upgrade this dependency past v1.14.0 without causing these tests to fail.
Obviously, no matter which version we specify in go-libp2p's go.mod, users of our library might still have client_golang bumped to a version greater than v1.14.0, causing a performance regression.
