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").

thanks for all the clarifications.
