I have wordops running on VPS/4Gb/Debian 10 and moved some Wordpress sites with the Duplicator plugin (some an EE site, some from a cPanel shared host). All sites are fastcgi_cache/-wpfc created, with the Nginx Helper plugin added. All are Cloudflare linked.
Performance is, well, lower than expected so far. The google PageSpeed ranking is 35-64. I get similar readings from the overbooked shared hosting. Most sites have adsense on the landing page, which I guess will affect the loading speed.
My question is, after the WP sites runs, what are the next steps you guys do to bring it up to speed?
