Not all connections to our page work. Many people can connect only after like 10 trys.. The page keep load and then it shows a connection times out error. I already tryed much but nothing helped.

Nginx config:

    user  www www;

worker_processes 4;

error_log  /home/wwwlogs/nginx_error.log  warn;

pid        /usr/local/nginx/logs/nginx.pid;

#Specifies the value for maximum file descriptors that can be opened by this process.

            }

        #access_log  /home/wwwlogs/access.log  access;
    }
include vhost/*.conf;
}

php-fpm conf:

[www]
listen = /tmp/php-cgi.sock

    user = www
    group = www
    pm = static
    pm.max_children = 8
    pm.start_servers = 2
    pm.min_spare_servers = 2
    pm.max_spare_servers = 6
    request_terminate_timeout = 100
    pm.max_requests = 2500

Would be nice if anyone got tipps.

Server stats: 8gb ram & 4 cores. 1000mbps connection.

You should provide us logs from nginx, other possibility is to run nginx in debug mode, but I wouldn't recommend to do this on highload website (this can be some test env) –  Sergey Jan 20 at 21:43

You're going to want to allow more than 8 php-fpm workers. Right now, you're only going to be able to process eight requests at a time, and with eight gigabytes of RAM to work with you've got plenty of space for more.

updated to 30 but nothing changed. –  user206170 Jan 20 at 17:19
    
Time to start narrowing it down, then. What's your CPU and RAM usage like? –  ceejayoz Jan 20 at 17:21
    
cpu usage 0.2% and ram still most free –  user206170 Jan 20 at 17:30
