My website is upgraded to PHP 7.1 but this version is still new and having less caching system that supported it. I want to install a caching for whole my VPS that help speed up my website. What are your recommendations?
I'm not too sure that there is any caching system besides Zend Opcache which would support PHP 7.1, since most of the current caching solutions support 5.x so far.
What webserver do you have currently insatalled on your VPS?
