GitLab now enforces expiry dates on tokens that originally had no set expiration date. Those tokens were given an expiration date of one year later. Please review your personal access tokens, project access tokens, and group access tokens to ensure you are aware of upcoming expirations. Administrators of GitLab can find more information on how to identify and mitigate interruption in our documentation.

Vladimír Čunát requested to merge perf-sendmmsg-answ into master Jul 12, 2019

Needs ~~squashing and~~ NEWS, but otherwise probably complete.

With a simple single-threaded benchmark I'm getting ~11% improvement in QPS. (In real life the impact should be much lower.)
