Good tutorial and welcome back to the tutorial section :d
Btw seems that this increases the site preformance.

it will increase most probably , basically it allocate more resource to the php-fpm process . a process that is used for processing all the php code that loaded using nginx or apache2
by default php allocate low resource . i think they assume it only used for low traffic website . because it hit very hard when my web app backend get massive traffic
