Optimize Nginx For High Traffic

I assume you have 4GB Ram, 8 Cores CPU and Storage dosen’t matter, let’s talk about you have 50K traffic everyday to your VPS and let’s tweak to accept more. If you have Ram of 1GB and 2 Core CPU and have traffic 20K to 30K per day then you can use the same tweak just use worker_processes as 2, worker_connections 25000 and worker_rlimit_nofile 25000

locate nginx.conf (/etc/nginx/nginx.conf) and edit OR add as following

user www-data;
worker_processes 4; (This tweak belongs to your CPU Cores, you can increase more if like to, recommended is 4)
worker_rlimit_nofile 50000;

error_log /var/log/nginx/error.log;
pid /var/run/nginx.pid;

events {
worker_connections 50000;
multi_accept on;
use epoll;

# Total users can serve = worker_processes * worker_connections

http {
include /etc/nginx/mime.types;

access_log /var/log/nginx/access.log;

sendfile on;
#tcp_nopush on;

#keepalive_timeout 0;
keepalive_timeout 65; (Default is 0)
reset_timedout_connection on;
types_hash_max_size 2048;
tcp_nodelay on;

client_max_body_size 10M; (This also means max php upload size and can conflict with PHP.INI max_upload_size)
client_body_buffer_size 32k;
client_body_in_single_buffer on;
client_body_timeout 180s;
client_header_timeout 180s;
client_header_buffer_size 32k;
large_client_header_buffers 4 32k; (worker_processes * no of large_client_header_buffers)

gzip on;
gzip_buffers 16 8k;
gzip_disable “MSIE [1-6]\.(?!.*SV1)”;

include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;
server_names_hash_bucket_size 128;

After editing the file restart nginx by simply service nginx restart (command is depends on your OS), recommended is to restart VPS and enjoy the high traffic website. I also used W3 Total Cache Plugin and tweak patch with Nginx, to know more about that check my other article which covers entire section about Nginx + WordPress + W3 Total Cache + High Traffic
