Yesterday, the WordPress Performance team announced the first beta release of the “Performance Lab” plugin, a proving ground for future performance improvements built into WordPress. The plugin is guided by real-world scaling lessons from experts like Google, and includes contributions from six 10uppers. This first public release focuses on image optimization and bringing attention to suboptimal caching setup and excessive script use. You can download the plugin from WordPress.org, provide feedback on Github, or dive into more detail in the announcement post.
