    Hi, I'm having some problems with my parallel every time I run windows virtual machine all my mac goes really slow I would like to know how to fix this slowliness haha, I don't know if my mac is the one that don't have the power to run both side by side at a descent speed, or maybe some configurations of the virtual machine i could change to make it run faster?? Here are the specs of my macbook.

    Model Name: MacBook
    Processor Name: Intel Core 2 Duo
    Processor Speed: 2.2 GHz
    Number Of Processors: 1
    Total Number Of Cores: 2
    L2 Cache: 4 MB
    Memory: 1 GB
    Bus Speed: 800 MHz

    In advantage thanks :)

    More RAM. 1GB is pretty light, especially when adding Parallels in the mix.

    edit: When running Parallels, check Activity Monitor and see what the ratio between pageins to pageouts is. I suspect there is a substantial amount of swapping going on.

    two things that might help or maybe not....

    first did you upgrade to 4 from a 3 version of parallels??.......i did that and it seems parallels needs time to rebuild something or rethink something or something and you need to leave it open and on its own for i dont know an hour or something to get its head together.... that helped me

    second thing again for parallels 4 the snapshot system is kinda broken or it works buuuuuuut after you do a snapshot it does some data synchornization thing or something which takes time maybe 5 minutes or so and during that windows and osx slow down

    once i found out about those two things i could use parallels 4 ok

    seems like a lot of small stuff like that in v 4 hopefully they will get it all fixed one day

    good luck!!

    oh yeah and ram cant hurt either

    mmm so I think my macbook is not good enough for running both at the same time and buying more ram is really out of my budget mmm but I still have a question wouldn't my macbook run better windows if i run it in bootcamp?? and about upgrading to parallel 4.0 would it make a difference if I have still the same specs??

    1GB of RAM is not nearly enough for OS X and Parallels. Run Windows in Boot Camp if you need to use Windows.

    well hey ram is cheap buy more ram - it will make your osx run better too

    i pretty much always go max ram now coz its about the cheapest way to get a real performance boost on a mac

    What much RAM would be enough?

    Would 2 RAm be enough for running parallel effectively and not slowing down the Mac or the VM?

    My Mac is:

    Model Name: MacBook Air
    Processor Name: Intel Core 2 Duo
    Processor Speed: 2.13 GHz
    Number Of Processors: 1
    Total Number Of Cores: 2
    L2 Cache: 6 MB
    Memory: 2 GB
    Bus Speed: 1.07 GHz
    Boot ROM Version: MBA21.0075.B03
    SMC Version (system): 1.34f8

    Thanks
