"cache For Anonymous Users"and "full Page Cache" To Speed Up Cs Cart And Successful Case?


anyone had either one of these addons installed
"Cache for Anonymous Users" " Full Page Cache"
they are not cheap so want to know more website's server response time after installed any of the addons.
The purpsoe of buy the addon was soely for Google pagespeed insights test Server Response Time
200ms as google suggested.
not aim for 100/100 of google pagespeed though.

Thank you
