nginx and multiple cpu

[Omer Faruk Sen]

Hi,

Have enabled accept_mutex on;

user  root;
worker_processes  8;

worker_rlimit_nofile 32000;

#pid        logs/nginx.pid;


events {
        accept_mutex on;
        worker_connections 30000;
}

but still only one cpu is busy while others stay in idle mode? Any sugggestions?

Regards.
