Hi everyone,

I’m trying to optimize mail-proxy.
My performance test is 1 client sends many request to 1 nginx server.


This is my current settings:

worker_processes auto;
worker_rlimit_nofile 100000;

#error_log /var/log/nginx/error.log debug;
#error_log /var/log/nginx/error.log warn;
error_log /var/log/nginx/error.log crit;
events {
worker_connections 1024;
#worker_connections 4000;
#multi_accept on;
#use epoll;
}

mail {
auth_http localhost:80/auth/smtp;
proxy_pass_error_message on;
proxy on;
smtp_auth login plain;
xclient on;
server {
listen 25;
protocol smtp;
}
server {
listen 465;
protocol smtp;
ssl on;
ssl_certificate /etc/nginx/ssl/server.crt;
ssl_certificate_key /etc/nginx/ssl/server.key;

ssl_session_cache shared:SSL:20m;
ssl_session_timeout 180m;

#ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
#ssl_prefer_server_ciphers on;
#ssl_ciphers ECDH+AESGCM:ECDH+AES256:ECDH+AES128:DHE+AES128:!ADH:!AECDH:!MD5;
#ssl_dhparam /etc/nginx/cert/dhparam.pem;
#ssl_stapling on;
#ssl_stapling_verify on;
#ssl_trusted_certificate /etc/nginx/cert/trustchain.crt;
#resolver 8.8.8.8 8.8.4.4;
}
}


Question>>
Low cpu usage, but the performance result is not good.
Do yoy know how to take full advantage of nginx?

Thank you for your time.
