AFAIK the short-and-sweet versions: add to USE "graphite" add to CFLAGS "-floop-interchange -floop-strip-mine -floop-block" add to USE "lto" add to CFLAGS "-flto" (must also have some form of -O optimization enabled) What they actually do and when it is appropriate to use or not use them is left an as exercise to the reader. :)
