The exact same rig reports that putting portages work directory on tmpfs does NOT result in faster emerge times. Period. I DO NOT care why that is, I just know from testing that it does NOT make emerge work any faster. The only reason to use tmpfs for portage's work directory is to save wear and tear on a drive. There is no difference in emerge times otherwise. Others ran their own tests and got the same results. Dale :-) :-) -- I am only responsible for what I said ...
