Optimize Scripts & Styles optimizes your site’s JavaScript and CSS files by combining, minifying and caching them. This will help your site’s overall performance and user experience by reducing the number of files served up and the overall size of these files.
For developers, this allows you to maintain uncompressed versions for development themes or plugins, while compressing them for a production environment.
For you SEO buffs, it cleans up the number of scripts that get included and downloaded to your site visitors, helping your overall PageSpeed score.
Header and footer script locations are maintained as well as any localized data used for the scripts and the minified files are stored in the /cache folder, making it friendly for plugins like WP Super Cache. Media attributes are also maintained for print stylesheets.

This plugin simply removes the scripts and styles that buddypress adds to your site, but only for non logged in users. Logged in users who need the buddyoress functionality are not effected
Thus speeding up the experience of normal vistors
This plugin would be more appropriate on a site that has a private buddypress area whilst also having general public facing content.

LH Dequeue Buddypress

Dequeue the scripts and styles that buddypress adds for non logged in users.
