PerfBoost Scheduled Plugin Manager – Boost WordPress Performance Plugin for WordPress is a breaking edge automatic plugin manager. It will boost the performance of your website, by deactivating other idle plugins, and activating them just when they are needed.

PerfBoost Scheduled Plugin Manager – Boost WordPress Performance plugin allows the page admin to set rules to dynamically create rules on when other plugins should be activated and when they should be deactivated. There are a number of different ways you can use this plugin:
Automatically, based on a daily schedule
Automatically, each time you publish a new post. You can also set a timeout for how long should the plugin stay activated
v1.0.1 update: Automatically, per page basis – enable or disable plugins only on specific URLs/ posts/ pages from your site
More on the plugin
We developed the PerfBoost plugin with simplicity in mind. We use all of these optimizations on our own sites and are excited to provide an easy way for you to now have them too! Performance optimizations should not be complicated and so every plugin on your site can be enabled/disabled with a single click.

The main way this plugin helps speed up your site is by disabling other plugins that might not be used on your site. For example, you might have some plugins for publishing new posts you publish on your site on social networks. These are activated only when you publish new posts. These can be easily deleted the rest of the time, and automatically enabled only when you publish a new post. By limiting activated plugins you can ensure a fast and snappy website.

Another perk to this plugin is the fact that we are constantly adding new features to the PerfBoost plugin to help you speed up your WordPress site even more! Bringing a performance boost to your website is our job.
This plugin will reduces the page size, because unnecessary CSS/js files are not loading. Also, it will reduces the total number of HTTP requests, making your website up to 90% faster.
