Would It Be Safe To Implement This (Nginx Latest & Php 7)

2 things got me great improvement (<100ms TTFB):

  1. Enable http2 in all of my SSL server blocks (needs nginx 1.9.5+)

    server {
    listen 443 ssl http2;
    #rest of your config here
    }

  2. Set up fastcgi_cache

    In /etc/nginx/nginx.conf:

    fastcgi_cache_path /etc/nginx-cache levels=1:2 keys_zone=phpcache:100m inactive=60m;
    fastcgi_cache_key "$scheme$request_method$host$request_uri";

    In your server's .conf file likely in /etc/nginx/conf.d/modify the php handling block

    location ~ [^/]\.php(/|$) {
    fastcgi_cache phpcache; # The name of the cache key-zone to use
    fastcgi_cache_valid 200 30m; # What to cache: 'Code 200' responses, for half an hour
    fastcgi_cache_methods GET HEAD; # What to cache: only GET and HEAD requests (not POST)
    add_header X-Fastcgi-Cache $upstream_cache_status; # Add header so we can see if the cache hits or misses

    # the rest of your existing stuff to handle PHP files here
    }

  3. restart nginx sudo nginx -s reload

This reduced my TTFB to under 100ms consistently, and everything seems to be pretty happy :)

Try it on a test server? : )
