[erlang-questions] Improve performance of IO bounded server written in Erlang via having pollset for each scheduler and bind port to scheduler together with process
Thu Jul 12 08:19:16 CEST 2012
We already surpassed the 100krps on an 8-cores machine with our HTTP server (~150K rps).
My question was: could we reach the 100K rps on a 4-cores machine with ehttpd ?
That will be awesome.
