I have used WP Rocket, WP super cache, Phastpress and some others I rejected in the past as well.
No one is as good as Rabbit Loader.
And. As a bonus, I get to cancel Imagify since Rabbit Loader does the same job. Plus, it uses CDN to make images show faster.

This is a great fully automatic tool with a good Dahsboard for me to see all web pages in a clear, easy way.

I love it so far. Please not people. Rabbit L takes up to 48 hours before each site is 100 % optimized.
