FoamFix is a mod which makes Minecraft go fast - by which I mean use less memory. It is also not a coremod (if used lawfully), because a certain guy writing a certain tutorial said that's a very very bad thing a while ago, or something like that.

I am aware that the site looks like a massive joke. I might change it to something else later, but the mod is serious - it leads to an idle RAM usage reduction of about 25-35% on average, with additional RAM requirement reductions for the loading process. However, no matter what, the logo stays. It's the best logo.
