Hi everyone I'm running a new 2.8 Quad Mac Pro with 16GB RAM. I recently swapped out one of the new 27" I7 IMacs (also with 16GB RAM) for this machine as I wanted to be able to easily add my own SSD boot drive. I do a lot of virtual machine work and java programming and notice that regardless of the machine/processor, Mac OS just simply does an amazing job of eating memory, but not a very good job of releasing it. For the one day that I had to run the system with the stock 3GB of RAM, it seemed like the OS was much better at "sipping" the memory that it needed. With 16GB, it behaves like me at a pizza buffet (unhinge jaw and swallow whole)! I've watched my memory go all the way down to 11MB available while I had 13GB inactive and it was paging like crazy. Why does the OS do this? I thought the Mac OS was supposed to be great at memory management, but it actually seems worse than windows??? If I've got 13GB of RAM sitting in inactive state, shouldn't it be getting used instead of the system writing to a page file? Is there anything I can do to force Mac OS to manage memory better? Thanks!
