[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

[Zabrane Mickael]

Hi Wei,

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.

Regards,
Zabrane
