Must Have Plugin for large sites and solid cache solution

This has become one of my must have plugins when managing large sites.
I’m also finding it a solid cache solution.

It’s helping me deliver a 4GB image rich very long Ecommerce home page in less than a second

Thanks for all the hard work which must have gone into this comprehensive product.
Very easy to use, and has largely replaced the other cache plugins I previously used (W3TC, Supercache, Rocket cache)
