https://twitter.com/m_ou_se/status/1526211117651050497 These are synthetic benchmarks but it's quite significant in them. From a different tweet: > It's the total time for 32 threads each doing 10'000 lock+unlocks (on a 64C/128T threadripper). So, the numbers you quoted correspond to a lock+unlock operation going from 8.75ns to 2.45ns, under low contention. > The numbers can vary a lot in different situations/hardware though. |
