Greetings, Wordpress Wizard

Why my object cache tests might be failing and should you worry about it?

Updated 20.May.2023

Starting with version 1.1.2 plugin offers you an option to skip out from testing persistent object cache. Why and when do you want to skip it?

Persistent object cache is a great caching layer and it's intention is to offload your database server and cache often used data.

Unfortunatelly to make object cache persistent accross page visits - you need to have a special plugin and backend, that allows it to functions correctly. A great example is Redis and Redis object cache plugin. If your hosting has Redis daemon running and your PHP has redis plugin installed - definitely give it a try!

If you hosting has enabled OPCACHE - try looking at Docket Cache plugin - this might work well in shared hosting environments.

You might not be able to get persistent object cache to work. If your website is not experiencing technical issues, if you are not running large webshot or if you are hosted in a shared environment - you may want to skip these tests. CPU and MySQL bechmarmarks are those, which are more likely to tell if your hosting is fast enough.
