Anyone using this plugin. I found it good. My pagespeed boosted from 72 to 86 using free version.
I use total cache
I started using it about 3 months ago. I find it better than wp total cache.
My blog is flying with total cache.. 95/100 in Google pagespeed insight.
Let me test total cache as well.
Here is a decent guide to follow about setting up this plugin. http://www.onlinemediamasters.com/w3-total-cache-settings/
I use WP Rocket, it's a mind blowing.
W3 Total Cache is currently considered as the best WordPress Cache Plugin. But, if you are using a shared web hosting, W3TC may consume lot of server resources. However, this plugin is safe to use.
