I don't expect a bit difference, but I'd really like to make sure that no big regression is introduced (like let's say, an increase over time of worker threads stuck in a certain status like G or more busy workers at request peak load time). Related to the above: have you noticed any improvement in latency/throughput metrics? For example, an improvement in total amount of requests handled in the same period of time o more generally in the responsiveness of the websites served? I don't expect big changes but I am curious :) Thanks again! Regards, Luca
