Performance tests

Test environment :

      8 core 16 thread Intel(R) Xeon(R) CPU  L5630  @ 2.13GHz

Test tool : WRK

Test performed with command:

wrk -c10000 -d600 -t8 http://$IP:80/index.html

As a backends we using 3 docker containers with Nginx with static page.

 user  nginx;
 worker_processes  4;
 error_log  /var/log/nginx/error.log warn;
 pid        /var/run/nginx.pid;
 events {
 worker_connections  4096;
 }
 http {
 include       /etc/nginx/mime.types;
 default_type  application/octet-stream;
 log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                 '$status $body_bytes_sent "$http_referer" '
                 '"$http_user_agent" "$http_x_forwarded_for"'; 
 access_log  /var/log/nginx/access.log  main; 
 sendfile        on;
 keepalive_timeout  65;
 include /etc/nginx/conf.d/*.conf;
 }
