The full review
W3 Total Cache rewards administrators who already know which layer is slow. Out of the box it scored 78 on our reference site; after a Redis object cache and minification pass, the same install reached 88.
That gap is the whole story. If nobody on the team will tune it, a simpler plugin will produce a better result.

Frequently asked
Does it need Redis?
No, but object caching is where most of its remaining advantage lives. Without a persistent object cache the free alternatives are simpler and comparable.
