Comment 6 for bug 607560

rCX, I'm not sure I'd call every 1-2 minutes tolerable, though it is certainly better. Why does there need to be any excess disk activity at all? On a netbook install, 1-2 minutes will still prevent the system from going to sleep automatically because the disk activity fools the system into thinking it's not idle. Besides, its loud.

Is there a mechanism to disable this process or is it required if journaling is used? Why doesn't ext3 have this behavior? It's also a journaling filesystem, right?
