Hi Christophe, Jim and Yann, Thank you very much for your consideration of putting SO_REUSEPORT patch in the 2.4 stable release.
I am also very happy that you find the white paper :-) All the most recent testing results are included in the white paper. Also, we have tested the (graceful) restart on the patch (previously, there was a bug.), it should be fine now. Please test it to confirm. Please let me know if you need anything else. Your help is appreciated.

I did some testing with an injector at the time of the proposal (on a 2.2.x version of the patch, so mainly with worker), and can confirm that it really scales much better. Where httpd without SO_REUSEPORT stops accepting/handling connections, it continues to shine with the option/buckets enabled. (I don't have the numbers for now, need to search deeper, btw the ones from Intel are probably more of interest...) So regarding the upgrade on infra, the difference may not be obvious if the tested machine is not "at the limits". One thing that probably is worth testing is (graceful) restarts, though. Regards, Yann.
