What benchmarks are you using to test poll/select/epoll?
for epoll/select latency tests we are using sockperf as performance
latency tool: https://code.google.com/p/sockperf/
It is a client-server based tool and it supported ping-pong, throughput,
and under-load test type.
For epoll, you will need to define a 'feedfile' ("-f filepathname")
which has a list of TCP and/or UDP socket and defined your IO mux type
("-F epoll").
Thank you!
This is very helpful.
With sockperf i can directly observe how poll/select/epoll are behaving.
I can see some improvement in all of them but clearly more work is
needed here.

I'm happy you got it working.
If you add '--timeout=0' to the sockperf epoll command line you can see
non-blocking epoll application behavior and then you will get some
improved latency over due to the application thread not sleeping.
This is not like a full blown LLS epoll solution but half way there.
