The full review
Perfmatters does not cache anything. It removes work. On our reference site, disabling contact-form and slider scripts everywhere except the two pages that need them cut requests from 34 to 22.
Pair it with a caching plugin rather than choosing between them; the two solve different problems and the combination scored highest of any configuration we measured.

Frequently asked
Do I still need a caching plugin?
Yes. Perfmatters trims what loads; a cache decides how quickly WordPress can hand over the page at all.
