E3-1240 with 32GB Ram - Unable to set the optimal value for the server

[agriz]

I am struggling to handle a traffic of 10K+ It will reach a lot. But my bad
configuration is limiting them.

www.conf

pm.max_children = 400
pm.start_servers = 40
pm.min_spare_servers = 40
pm.max_spare_servers = 70
pm.max_requests = 800

nginx.conf

worker_processes  3;
events {
    worker_connections  8096;
    accept_mutex on;
    accept_mutex_delay 500ms;
    multi_accept on;
    use epoll;
}

sendfile        on;
    tcp_nodelay on;
    tcp_nopush     on;


    client_body_buffer_size 128K;
    client_max_body_size 8m;

    client_body_timeout 15;
    client_header_timeout 15;
    send_timeout 10;
    keepalive_timeout  15;    

    open_file_cache max=5000 inactive=20s;
    open_file_cache_valid 60s;
    open_file_cache_min_uses 4;
    open_file_cache_errors on;

If i change the values, it hangs with 3k or 5k visitors.
This one handle 5k to 8k

But cpu and ram are available in server.
Quad core and 32GB Ram SSD
