Willy Tarreau 4d82bf5c2e MINOR: connection: align toremove_{lock,connections} and cleanup into idle_conns ... We used to have 3 thread-based arrays for toremove_lock, idle_cleanup, and toremove_connections. The problem is that these items are small, and that this creates false sharing between threads since it's possible to pack up to 8-16 of these values into a single cache line. This can cause real damage where there is contention on the lock. This patch creates a new array of struct "idle_conns" that is aligned on a cache line and which contains all three members above. This way each thread has access to its variables without hindering the other ones. Just doing this increased the HTTP/1 request rate by 5% on a 16-thread machine. The definition was moved to connection.{c,h} since it appeared a more natural evolution of the ongoing changes given that there was already one of them declared in connection.h previously.		2020-06-28 10:52:36 +02:00
