Hi, hackers! In the measurements above in the thread, I've been using LIFO wake queue in a primary lockless patch (and it was attached as the previous versions of a patch) and an "inverted wake queue" (in faсt FIFO) as the alternative benchmarking option. I think using the latter is more fair and natural and provided they show no difference in the speed, I'd make the main patch using it (attached as v6). No other changes from v5, though.
Regards, Pavel.
