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
No release in a yearHow 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.

I don’t understand why this is not more popular, it gives you valuable insights in the system and where the chokepoints are. Great job!

Don’t use P3 use F12-Profiler!

Installed the plugin, nothing happens. No link in the admin bar, nothing in the admin menu, no new settings. Wasted my time.

Plugin is working and I see some stats. However I have a certain plugin that’s delaying all the pages with more than 10 seconds and there is no mention of it in the stats, everything looks fine there, but it’s not.

Great details. The only thing causing me to rate it as 4 stars and not 5 stars is missing a way to save the results to file. Add this and I’ll change it to 5. Promise!

Excellent! After P3 doesn’t work with PHP7+ anymore, F12 seems finally the one stepping in to fill that gap. Update [18-Jun-19]. After some small contributions of mine to the dev efforts, the plugin developer has decided to add me to the team, long after this review was written. This topic was modified 7 years, 1 month ago by alx359. Reason: Became part of the team
