Zinn® Cache: See what is slow

What it does

• A status screen that says what is caching — One screen names what serves your pages (LiteSpeed, nginx, Varnish, Apache, Cloudflare or the disk cache), how big each cache is where WordPress can read it, the purge queue and the last purges, and checks the hit ratio on a sample of your pages. When it cannot see something it says so instead of showing zero.
• Cache analytics (Pro) — Hit ratio, reads and writes, memory used, keys evicted, the average Redis command time and the slowest recent commands, on one screen.
• Slow-query and uncached-call finder (Pro) — One page view in 20 is measured. Slow queries, slow calls to other websites and cache misses are each traced to the plugin or theme responsible.
• Health alerts in your dashboard (Pro) — On a site hosted with Zinn Digital®, cache health is reported every hour and you are emailed when the hit ratio drops or Redis fills.
• Cloudflare hit ratio on the status screen (Pro) — See how much of the last 24 hours Cloudflare answered from its own cache, next to your server cache, without opening the Cloudflare dashboard.
