Tags cache used too much disk space

By p1c2d3 (postcd) on June 14, 2025

For some reason, plugin caused Tags cache to be 500MB on disk (details on the support forum when you search for "500MB").
Otherwise plugin is easy to use and I think helpful, advisable.

Speed Demon with a Few Quirks

By avirmedia on June 9, 2025

WP Fastest Cache is solid for boosting site speed! Love the mod_rewrite approach and auto-cache clearing when you publish posts. CDN integration with Cloudflare/Bunny is smooth, plus the preload feature is handy. BUT heads up - it can mess with analytics by caching AJAX/JS requests. You can add filter rules but they don't always work perfectly. Great for speed, just watch your stats!
