Perfmatters

Perfmatters is a lightweight WordPress performance plugin that helps to speed up your website by disabling unnecessary features and scripts. Some key features of the plugin include:

• Script management: Perfmatters allows you to selectively disable scripts and styles on a per-page or per-post basis. This can help to reduce the number of HTTP requests and improve loading times.
• DNS prefetching: Perfmatters can help to reduce the time it takes to resolve DNS by prefetching external domains. This can improve the overall loading time of your site.
• Lazy loading: Perfmatters includes a lazy loading feature that delays the loading of images and videos until they are visible on the screen. This can help to reduce the amount of data transferred and improve loading times.
• Heartbeat control: WordPress uses a feature called the Heartbeat API to communicate with the server. Perfmatters allows you to control the frequency of this communication, which can help to reduce server load and improve performance.

To use Perfmatters, simply install the plugin on your WordPress site and navigate to the settings page to configure the features you want to use. The plugin includes a variety of options to help you fine-tune the performance of your site.
