I fixed perf by 2x in 4a99291. For some reason OTEL counter still does a memory allocation for each Inc() call. We should open an upstream ticket for that.

Actually, your benchmark is incorrect. You are not initializing OTEL SDK, so the benchmark is actually going to noop implementation (even more surprising why it performs an allocation in no-op mode).

Yes I do realise that, I wrote the benchmark first and just ran it with no-op implementation for the looks of it expecting a very low time to be taken.
But, the no-op implementation itself had a very poor performance, so I thought I would raise it first, and didn't bother to check with the correct implementation

I am quite sure that the perf hit is coming from that one still remaining allocation.
