I just purchased a new Macbook Pro to replace my aging 2006 model. I am running Lion with the latest updates, I have a 2ghz i7 processor with 4gigs of RAM.
I need this machine to do .Net development in Windows so I am running a Virtual Machine. I have tried both Parallels and VirtualBox (both the latest) to run Windows 7. On both of those machines I gave the VM 1GB RAM (and it runs fine-ish)
When I have the VM or any other program that uses a lot of RAM (like Steam, or Minecraft) the entire machine in OS X bogs down. When I say "bogs down" I mean launching new applications or opening new windows/tabs takes too long. After the new tab/window launches it runs fine.
An example would be that with Chrome open, if I open a new tab it may take up to 10 seconds for the tab to show up. Just opening the main menu to go to "About This Mac" took 3 seconds to open the menu and 2 seconds to open the window.
I would expect my VM to run slowly with only 1 gig of RAM, but I would not expect these issues to transfer over into my main OS.
Is Lion a known resource hog or does it sound like something may be wrong with my new machine?
For reference sake, the machine recognizes the full 4 gigs of RAM. Currently Activity Monitor says that my RAM stats are this:
- 100mb Free
- 2.3GB Wired
- 1.12GB Active
- 450mb Inactive
(those numbers are rounded)
I checked with a coworker running a Parallels VM of Windows 7 with 1GB RAM on his 2007 Macbook Pro and he has similar RAM numbers, but his machine is fast and responsive while mine is not. Even typing this message, there is a noticeable delay between me pressing a key and seeing it typed on the screen.
