13 The point isn't about using cache DURING the emerge. The point was
14 whether having portages work directory on tmpfs resulted in speed
15 increases. If you have portages work directory on tmpfs, of course it
16 uses ram. That's what tmpfs is. It's taking what might normally be put
17 on the disk and putting it in ram because ram is faster. The point is,
18 cache or not, having portages work directory on tmpfs doesn't result in
19 speed improvements as one would expect. Actual tests gave unexpected
20 results. Tests show that putting portages work directory on tmpfs did
21 not result in speed increases for emerging packages.
