Poor performance, bloated inferface

This plugin is poorly optimized - it will slow down your server and browser page load unnecessarily.

There’s no reason to attempt to modify the content/excerpt if the “Automatic shorten links in article” option is disabled – this easily translates to hundreds of calls to function ‘replace_by_short_link’ (1 SQL query each) = SLOW SERVER. Also, a short link is created in the database for every page/post despite setting shortlink ‘types’ – this can easily create a very large database table unnecessarily.

If not making use of displaying the short URL automatically, does not stop the CSS style from being loaded into the page header = SLOWER PAGE LOAD.

The adding of a parent menu called “SL Plugins” is bloated and ugly.

Finally, you do not create an instance of your class (which is best coding practice) so that I can at least remove actions/filters for better performance. Giving this 2 stars until improved.
