[Erlyaws-list] Yaws concurrency problems

[ALBERT H. B. <ab...@ti...>]

Hi,

I'm trying to set up a benchmark of Yaws with Apache Benchmark (AB) tool. The configuration of Yaws is the default one, only changing the root folder where to get HTML scripts, and also adding where to look for PHP FastCGI. Max_connections  and keepalive_maxusers instructions are set to nolimit.

My problem is when I am running the test. When I set a concurrency level higher than 200 clients, the ab exits with an error, only doing few requests (by using the -c option). Searching I found some Erlang variable which is ERL_MAX_PORTS which can increase the open ports in the Erlang virtual machine (by default is 1024). But I'm not able to run Yaws with this instruction (inside Yaws executable or when executing it with --erlarg ).

Is there a way to increase the concurrency of Yaws?
Thanks a lot.
Regards,
