Slider Revolution plugin is really advanced plugin with tons of options and features and it is technically impossible to make it as fast as you probably would like. However, we suggest to use W3 Total Cache plugin to speed up your site. If you look at https://tools.pingdom.com/#!/bVD4fk/http://themes.muffingroup.com/betheme/ you will see page speed is less than 1 second even with Slider Revolution so using this plugin definitely would speed up your site.
