Nginx TCP Delays

[Khalid Shaikh]

We are using Nginx on this web server.  Look at the # of reading & writing
requests.  a curl http://localhost/test.html can take up to 45 seconds.
Can anyone help?

Using telnet I can see that basically the Nginx server is taking time to get
to the TCP connection that I initiated.

This happens only during peak times of the web site.

Active connections: 8467
server accepts handled requests
 380771 380771 835836
Reading: 75 Writing: 1497 Waiting: 6895
http://67.159.60.59/status      45.03 seconds

I've attached the nginx.conf

user www-data www-data;
worker_processes 32;

error_log  /var/www/log/nginx_error.log;
pid        /var/run/nginx.pid;

events {
  worker_connections  10024;
}

http {
  include       /etc/nginx/mime.types;
  default_type  application/octet-stream;

  sendfile         on;
  tcp_nopush       on;
  tcp_nodelay      on;

  server {
    listen       80;
    server_name  xs.to;
    root   /var/www/xs;
    error_page  404 index.php;
    error_page   500 502 503 504  index.php;
    access_log off;

    location / {
      root   /var/www/xs;

      rewrite  ^/albums/(.*)$  /albums/showalbum.php?$1?  last;

      error_page  404 index.php;

    }

    location /status {
      stub_status on;
      access_log off;
    }

    location ~ .php$ {

      fastcgi_param  SCRIPT_FILENAME    /var/www/xs/$fastcgi_script_name;
      include /etc/nginx/fastcgi_params;
    }

    location ~* ^.+.(jpg|jpeg|gif|tiff|png|bmp|ico|fav|html)$ {
      access_log        off;
      expires           30d;
    }
  }
