Update activity
How busy the existing users are, measured as downloads in the last 30 days for every 1,000 active sites. A spike means a new release everyone's pulling; a long, slow decline means an aging user base that updates less.
Release cadence
Occasionally updatedHow often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Estimated value
What this plugin might earn a year, and what it might sell for. Modeled from public signals; we don't see anyone's books.
Est. annual revenue
Est. acquisition value
No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from.

When Memcache module is not loaded with PHP I get a fatal error instead of an explaination. I use PHP 7.1 and my host doesn’t offer Memcache, only Memcached. Also files must be copied manually to wp-content.

This plugin has no settings. Zero. It Just Works. Running it on my eCommerce website and not a single problem. Faster admin, just as fast front-end as running W3 Total Cache, and I don’t need to tweak settings. Thanks @jjj!
