What Full Page Cache are you running? 

I can see that you are running PHP 5.6? You may want to consider switching to a newer PHP version (if all of your extensions support it) as they perform better and uses less resources. 

If you are running a version older than 1.9.4, here's the official patch for PHP 7.2 support:-
