"WitrynaCouple of observations: The lockfree hashmap is 3x as fast as sync.Map, and costs 37% less memory. The decrease in time (and increase in memory) of using bucket size 16 vs. 24 is very minimal, less than 4%. Golang's native map + RWMutex to synchronize access is even slightly faster than sync.Map, and costs least amount of memory. " - Lock free cache
