In the past few years, we have covered plenty of plugins and scripts that can compress your images, cache your pages, and speed up your website by loading slow plugins only on certain pages. The Index WP MySQL For Speed plugin is also worth a look. It speeds up your website by adding high-performance keys to the tables that you choose.
This script monitors your website’s MySQL database to determine what could be slowing things down. Using these indexes, WordPress will be able to perform database retrievals more efficiently. You can further speed up your website by cleaning up your database, reducing it size and using caching plugins.
