I let mine default to half of ram but when I need to compile LOo, then I have to manually increase it. I guess 8Gbs isn't enough. Come to think of it, I updated LOo the other day and it didn't complain about it being less than 8Gbs. I guess it doesn't need as much as it used to. Code clean up?? I might also add, I see no speed improvements in putting portages work directory on tmpfs. I have tested this a few times and the difference in compile times is just not there.
