I've got a question about swap and RAM requirements in 2.4. Now, when 2.4.0 was kicked out, the fact that you need swap=2xRAM was mentioned. But what I'm wondering is what exactly are the limits on this. Right now I've got an x86 box w/ 128ram and currently 256swap. When I had 128, I'd get low on ram/swap after some time in X, and doing this seems to 'fix' it, in 2.4.4. However, I've also got 2 PPC boxes, both with 256:256 in 2.4. One of which never has X up, but lots of other activity, and swap usage seems to be about the same as 2.2.x (right now 'free' says i'm ~40MB into swap, 18day+ uptime). The other box is a laptop and has X up when it's awake and that too doesn't seem to have any problem. So what exactly is the real minium swap ammount? -- Tom Rini (TR1265) http://gate.crashing.org/~trini/
