Biggest opportunity: Swap “cache”, “performance” and “preload” for “warm”, “cache warming” and “fastcgi”. “cache” isn't earning its slot: you're not in the first 24 results for its own search. “warm” sits at #5 untagged, close enough for a declared tag to move it up. “performance” isn't earning its slot: you're not in the first 24 results for its own search. “cache warming” sits at #6 untagged, close enough for a declared tag to move it up. “preload” isn't earning its slot: it only gets you to #24. “fastcgi” sits at #14 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

How it's measured →3.2%
of downloads still active
At least 80 of 2.5K 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.
This plugin shipped 3 releases in the last 12 months, and every existing install that updated counted as another download. wp.org publishes no split between first installs and updates, so we show the raw rate rather than guess at one.

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.

What to do about it
- Swap “cache”, “performance” and “preload” for “warm”, “cache warming” and “fastcgi”. “cache” isn't earning its slot: you're not in the first 24 results for its own search. “warm” sits at #5 untagged, close enough for a declared tag to move it up. “performance” isn't earning its slot: you're not in the first 24 results for its own search. “cache warming” sits at #6 untagged, close enough for a declared tag to move it up. “preload” isn't earning its slot: it only gets you to #24. “fastcgi” sits at #14 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 “crawler”. #15 puts you just past the first ten results, where almost all the clicks stop. The gap to close is small.

I started to use this plugin alongside with WP Super Cache and it pairs up really well! I’ve had few questions during the setup and got the answers in merely few hours. I think this is a quite useful plugin to improve TTFB if you are using a cache. Plus, it also warms up the Cloudflare cache too.

I’m using this plugin alongside Cache Enabler and it works perfectly to warm-up the pages after clearing the cache. As a result, my TTFB of some pages have gone from 3 seconds to 308ms. I had a question about the crawler queue and received a reply within a few hours of submitting the request and continued to reply to messages with explanations and an acceptable workaround… and then released a new version (the same day) to fully fix my issue. Very happy with the plugin and support.

Super easy to get going. Installed it, picked my content types, set a schedule, and that was it. The UI is clean and doesn’t feel bloated like others.

Does not work out of the box as described for my setup I purchased pro and installed on my dedicated server running latest WordPress with PHP 8.4.* – 54gb ram, 16 core CPU. Proper solid rig with other advanced setup options. Can not start crawler (unable to connect issue). Crashes website on post publish or edit (critical error white-screen story). wp-cli function not compatible with php 8.4. Appears you need to use php 8.2 ( tried to use it, but above errors continued). This day and age, when you pay for a premium product, you expect speedy support….otherwise you are binned. Zero customer support – even an automated response would be welcomed. This topic was modified 9 months ago by Kalacta.

Warming cache is an excellent way to increase your cache HIT ratio and ensure visitors hit cache as often as possible after cache expiration or content is updated. We’ve been using the Warmer plugin for a few months now, and after monitoring the CrUX data, we saw a decrease of ~29% in our time-to-first-byte (TTFB) on one of our sites. ⚡ Warmer was the only change that was made during this time period. The developer of Warmer understands how to create an easy to use UI that is fast and lightweight. You do want to be careful not to overuse this feature on shared hosts, but you can choose a less aggressive crawler setting if needed in the plugin. And only warm the cache of your most important content (post types).

Overall, pretty solid. The UI’s clean, super easy to navigate, and it does exactly what it says it will.
