Frequently Asked Questions
Common questions about WP-Optimize – Cache, Compress images, Minify & Clean database to boost page speed & performance
We've built WP-Optimize Cache around the most advanced and powerful caching technology. Our caching tests and feedback from real-world users show that the caching feature alone can make your site faster than any other cache plugin or optimization. See these speed test results.
Yes; optimizing does not involve any "tricks" or poking around in dangerous ways. It involves running routine clean-up operations using well-defined, common MySQL commands. Nevertheless, we always recommend backups, which cover every possibility; not just database malfunctions, but hackers, human errors, etc. We recommend UpdraftPlus.
This is a "how long is string?" sort of question. It depends completely on your site - how big it is, how many users interact on it, how long it has been running, and when you last optimised it. However, the savings and speed-ups can be substantial; it is always worth making sure that your database is optimised.
In our support forum, here: https://wordpress.org/support/plugin/wp-optimize/ WP-Optimize does not make large savings on my database This is rare; it's probably because you're with a shared web hosting company that doesn't allow scripts to run an optimize command via SQL statements (SQL "OPTIMIZE" instruction). Please consult your web hosting company on this matter.
Yes - WP-Optimize Cache is WordPress's #1 most-installed optimisation plugin, with over 800,000 users and a pedigree going back over 8 years.
WP-Optimize will disable some features if it detects InnoDB tables. Optimization of the database tables on-disk is not available, but other clean up features would work.
Not unless you have an existing backup. Please ensure that you make a backup of your entire database before using WP-Optimize for the first time, and when you upgrade to a major new version of it. We recommend UpdraftPlus.
The plugin is an ongoing work; that means that it is impossible to rule out unforeseen situations and bugs. So I would recommend you to test it out on your local system or make a backup of your database (just to be extra careful).
When WordPress uses a particular transient, that specific transient is re-created automatically. So, it's normally for ones which are in active use to gradually re-appear. The best way to keep things optimal is to clear the transient options on a scheduled basis. For example, WordPress may create 50 transient option in a week. If you schedule WP-Optimize Cache to clear these options on a weekly basis, you'll have far fewer building up. The table size shows wrong / Not optimizing Please check your database for corrupted tables. That can happen, usually your web hosting company can run the repair command on the db.
To use all features in the plugin, a minimum of version WordPress 4.9 with PHP 7.2 are required. But we do recommend to use the latest version of WordPress. Using PHP 7.2+ is also highly recommended, as our caching feature will work even faster.
