Lighthouse is a WordPress performance tuning plugin, removing lots of default WordPress behaviour, such as filters, actions, injected code, native code and third-party actions.
Read the 2.8 compatibility update announcement.
In order for a WordPress installation to work as expected, load fast and error-free, it needs a bit of cleanup in order to help the browser cache the requested content and the caching plugins to work with 100% efficiency.
Based on each user requirements, this plugins allows for removal of unused classes and IDs, redundant scripts and stylesheets, new and non-optional features and queries, disabling of various native requests and functionality.
This plugin also helps all pre-caching routines, by making the source code smaller and allow for improved minification and caching.
This plugin also helps with security, by adding several rules for HTTP(S) requests, XML-RPC and malicious requests.
Note that this plugin requires a bit of common sense, and some prerequisites are necessary before optimizing, such as image optimization, unused scripts and styles cleanup, custom Google fonts optimization and more.
Increased my speed by 100%, to increase even more use in combination with other plugins (w3) and learn about js minify, use cdn and and img size reducer plugin and you will have excellent results.Lighthouse Review
