Conversation
Threads are initialized sequentially to allow for a predictable mapping of threads and queues. Not all parts of the start up need to be done sequentially. The setting up of the rings can be very expensive, taking of a couple of hundred milliseconds. The ring setup doesn't need to be done sequentially though. This patch releases the thread early, after bind but before the ring setups. Ticket: OISF#7272.

@victorjulien are you not merging this ? |

I think I saw one case where this didn't start up, but I did not record it. So want to do some more testing. |
|
I've been running this in a loop for a long time, and under load. Haven't seen issues. |

Merged in #12222, thanks! |
