My emac has been up for 9 days with half a million page in and page outs. 1.5G Ram. 10.4.3 Everything is going along fine and I was intending to see what happens if I don't shut down for a long time. However I've just noticed that the VM is up to over 11 Gig when it is usually around 6. There's 17 Gig available. Under these circumstances is there any performace penalty for leaving the VM at 11 Gig or is it better to restart if the VM gets big. Also why does the VM grow like this. Isn't 6 Gig enough to play with?
