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.
