I was running a few apps this morning and my computer had not been rebooted for a good 24 hours, did a vm_stat in the terminal and to my shock my hit rate was a very respectable 12%. nice number considering I only have 512MB RAM. About an hour ago I did another vm_stat check it it was at a whopping 62%, what the heck??? I did a reboot but even right after that it was still in the 50%. Till now it was never higher than about 35%. Can someone help me understand why it would ever get to 62% especially after a reboot. I got better numbers than this when I only had 256MB. I was not doing anything out of the ordinary and now every time I check it its at least 53% or higher! I don't get it!
