If you need to find foamfix for those who do not have 6 or more gig of ram to spare running big mod packs just drop this into your pack yourself. (I just download individual.jars and skip twitch myself for offline play)
Links are in the video of how to find or just search foam fix on Google and click the link that is on the place holder page. I made this post for newer people who are interested in performance mods for lower end CPUs
Figured it could help someone.
