nginx slow on every second request

I'm currently creating an api for my website, using nodejs and nginx, I've setup reversed proxies for each nodejs app i'll have running (api, mainsite, other stuff..).

However, when i try my api, it will use a very long time on every second request, sometimes time out..

NGINX.CONF

# For more information on configuration, see:
#   * Official English Documentation: http://nginx.org/en/docs/

error_log  /var/log/nginx/error.log;
#error_log  /var/log/nginx/error.log  notice;
#error_log  /var/log/nginx/error.log  info;

pid        /var/run/nginx.pid;


events {
    worker_connections  19000;
    multi_accept    on;
}


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;

}

Adding this because this is what worked for me

https://forum.nginx.org/read.php?15,239760,239760 Seems to indicate that you can proxy_pass to 127.0.0.1 instead of localhost and the request goes through fine

macbresch

One year old but I wanted to point out that there is a work around for that issue. Like Cruz Fernandez wrote you can set 127.0.0.1 instead of localhost on the proxy_pass directive. This prevents the 60s delay on every second request. I'm using Windows 8.1 and nginx 1.9.5.

you can use 127.0.0.1 (instead of localhost on the proxy_pass directive)

location /nodejsServer/ {
    proxy_pass http://127.0.0.1:3000/;
}

I was able to fix this by using an upstream statement.

eg. :

upstream nodejs_server {
    server 192.168.0.67:8080;   #ip to nodejs server
}

#server config
server {
    location /nodejsServer/ {    #http://localhost/nodejsServer/
        proxy_pass http://nodejs_server;
    }
}
