The bigger tell is that half the article is unnecessary space-filling hyperbole...
The overwhelming majority of the speed-up here would come from the database, which is trivially easy to run on tmpfs. When using Docker, it's literally a one-liner! For example:
docker run -d --tmpfs /var/lib/mysql -p 127.0.0.1::3306/tcp -e MYSQL_ROOT_PASSWORD=[password] mariadb:11.8
Of course you need a really good backup story for this to be a reasonable choice.
