Speed up Magento 2.0 by Nginx before Apache

My Nginx config for local development is below.
Nginx listens to port 805 and Apache listens to port 1805.

server {
	listen 805;
	server_name localhost.com;
	error_page 419 = @magento;
	error_page 420 = @static;
	location /pub/media/ {return 420;}
	location /pub/static/ {return 420;}
	location / {return 419;}
	location @static {
		root C:/work/magento/2.0/code;
		access_log off;
		expires max;
		try_files $uri @magento;
	}
	location @magento {
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        # important for Magento
        proxy_set_header Host $host:$server_port;
		proxy_redirect http://localhost.com:1805/ http://localhost.com:805/;
		proxy_pass http://localhost.com:1805;
	}
