Biggest opportunity: “benchmark”, “benchmarking” and “cache” aren't earning a slot. You list them, but you're not in the first 24 results for those searches. WordPress.org counts only your first five tags, so free the slot for a search you can win.

of downloads still active
At least 1K of 55.5K lifetime downloads are still running, above its category: the median Performance plugin keeps 1.4%, across 1,101 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Performance plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.
High removal-risk signals
63/100Maintenance and integrity signals that tend to precede a WordPress.org removal. Not an official status, a heads-up to act.
- Long abandoned. No update in 8+ years — the top precursor to removal once a vulnerability is found.
- Compatibility drift. Tested only up to WordPress 3.4.2, well behind 6.8.

How it's tracked →Directory searches this plugin turns up in, and which way each one is moving. WordPress.org publishes no history of search positions, so this starts the day we first tracked a keyword and never backfills.
Not enough tracked days yet to call a direction. Momentum needs at least three keywords measured a week or more apart.
wp.org is where the directory puts the plugin for that search. On merit is where it would sit if results were ranked on rating, support and updates, without the install boost. The last column is how far the wp.org position moved, from our first reading in the last 90 days to the latest.

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.

I still use this on all my projects! Works like a charm.

No Admin screen. Cool and Smart.

Our WordPress site runs on an iSeries and we have problems using the main caching plugins (Supercache, T3 Cache etc). All of our pages were taking up to 10 seconds to load, mostly because of the WYSIJA (Mail Poet) and Jetpack plugins. A code trace showed that WYSIJA seemed to take forever looping through POMO and MO functions. As soon as this plugin was installed the site sped up dramatically.
