Subject[PATCH 0/2] perf bench: Add epoll-wait-mp1c benchmark calling epoll_wait(2)
Date
The intention of a new benchmark is to measure events delivery
bandwidth: N threads produce events and 1 thread consumes events
calling epoll_wait(2).

Benchmark does measurements for 8, 16, 32, 64 and 128 threads in
a loop.

This one differs from epoll-wait in that it produces events from
many threads and consumes from one, thus mp1c (many producers
1 consumer).

Roman Penyaev (2):
perf bench: rename epoll-wait bench to epoll-wait-1pmc
perf bench: Add epoll-wait-mp1c benchmark calling epoll_wait(2)
