No, but I did some tests with one of my network performance tools. I imagine
that I can *construct* test-cases and add some 'perf stat cs:u' statistics.
IMHO it is not fair to present some artificial tunned performance numbers.
There are use-cases where EPOLLEXCLUSIVE can be really helpfull, yes I think
that this flag SHOULD be a userspace default. ;-)
