Hello, please how one can parelelize content elements loading in vBulletin? Is there any plugin for this or need to be done 100% manually by adding content to CDN, 10 elements per one CDN hostname?

This is example of badly optimised website (page elements are loaded serially not parelelly causing huge load time):
