Any reasons the mutex is used in quinn-protocol ? Thx #1338

Does the use of mutex in Quinn-protocol introduce any performance penalty? Also is it better to apply the mutex in Quinn?

Compared to what? Quinn uses locks when it is necessary to do so, and does not when it isn't. If your code is single threaded anyway it will not have any impact.
