Will using aync/atomic for incrementing and loading/storing the counts improve performance?

[HarshKumar17]

Is any benchmarking available for this circuit breaker? Will it help to use sync/atomic to keep the counts instead of using mutex for locking?
Or are there some race conditions not satisfied by sync/atomic that I am overlooking.

The circuit breaker uses mutex to maintain consistency among those related data:

sync/atomic cannot maintain consistency among multiple data.
