Biggest opportunity: Swap “cache” for “memcache”. “cache” isn't earning its slot: you're not in the first 24 results for its own search. “memcache” sits at #12 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

of downloads still active
At least 400 of 15.6K lifetime downloads are still running, above its category: the median Performance plugin keeps 1.4%, across 1,104 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.

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.

|---|---|---|---|
| mongodb your tag | #6 | #3 | 0 |
| apc your tag | #12 | #7 | 0 |
| wp mongodb | #4 | #1 | 0 |

What to do about it
- Swap “cache” for “memcache”. “cache” isn't earning its slot: you're not in the first 24 results for its own search. “memcache” sits at #12 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.
- One page off on “apc”. #12 puts you just past the first ten results, where almost all the clicks stop. The gap to close is small.

Release cadence

Only used very briefly so far, but, first impressions = Excellent! It’s the only cache plugin I found that works well with Wincache/IIS/Windows. It’s very clean and simple. The widget is useful, as are the statistics if you enable them. Does exactly what I want. The only thing I wish it would have as a really nice addon, is a way to pre-load the cache by visiting each post/page, though I can sort that externally. Not of failure of this plugin, but, it breaks the ‘simple download monitor’ download links for all files on my site. There is, due to the design of this plugin, an easy fix (though it errored on my site with a ‘needle’ not found or similar first time!). Enable ‘Exclusions’ and add ‘download_id’ to the excluded $_GET variables. Clear your cache, and downloads should work again. This is because download links are simply sent to the home page with the get variable. Probably a dumb way to do it, but… This topic was modified 3 years, 5 months ago by pjsgsy.

If you use this right and read the instructions – none the better for its purpose. Combine it with Autoptimze and you’re good to go.
