Yes. Though the point is to illustrate that $5/month 1click toggle button can almost give you same gains as a full pro optimised configuration by expert page speed folks. For average joe Wordpress users that is a very good value add for the price
I did some page speed comparison tests with Webpagetest, GTMetrix, Page Speed Insights and FastOrSlow tools for my Wordpress blog https://community.centminmod.com/threads/cloudflare-wordpres... using Cloudflare Automatic Platform Optimizations versus without APO (with my own custom Cloudflare Worker cache + Origin PHP-FPM fastcgi_cache cache setup). Results are very close so you get a lot of bang for your buck with CF APO 1 click toggle button if you're not well versed in page speed optimisations.
However, CF APO seems to have a few teething issues to sort out
For US$5/month CF APO, has a lot of value if you don't want to go down the rabbit hole for page speed optimisations and rolling out your own Cloudflare Worker cache configuration.
Really depends on underlying hardware of the Linode and DO VPS servers as they can vary greatly especially on DO depending on datacenter and region you end up in. Newer DO datacenters getting newer hardware so difference compared to older DO datacenters is huge - benchmarks of same DO droplet plan on different hardware https://community.centminmod.com/threads/digitalocean-us-15-...
