Subject: [PATCH 0/2] perf bench: Add epoll-wait-mp1c benchmark calling epoll_wait(2)
Date: Thu,  3 Jan 2019 16:00:28 +0100	[thread overview]
Message-ID: <20190103150030.17030-1-rpenyaev@suse.de> (raw)

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)
