    I have a late 2011 15" MBP (Lion) with Windows 7 64bit installed using Bootcamp. I also own a copy of Parallels Desktop 7 from one of those Mac App Bundles but I have not set it up yet. I'm thinking of setting up Parallels to use with my Bootcamp partition so I can quickly access and use a few things on Windows 7 without restarting my MBP.

    However before I do I wanted to first check to see what, if any, downsides there are to setting up Parallels. I'm not talking about the decreased speed when using Windows 7 in Parallels as opposed to Bootcamp but instead is there any slow downs to the whole system (such as boot time, shutdown time, etc.) even when not using Parallels? I vaguely recall reading that some people noticed a significant slow down in their Macs startup and shutdown speeds and possibly the overall speed of their Mac after setting up Parallels 7. Is this true? Is it just a possibility or a given? Is there anything to prevent it?

    Again, just to be clear, I dont mean a slowdown when using Parallels 7 but an overall slowdown to the Mac (when in windows/bootcamp or Mac OS) just from setting up Parallels. Possibly due to changes it makes to the system and system files or something.?

    I just don't want to end up setting up Parallels and then find my Mac running much slower and the only way to fix it is to do a clean install of Lion along with a clean install on Windows 7 on bootcamp. That would suck.

    Any info you can give me would really help. Thanks.

    No slow downs to the system in Native OS X.. And nothing noticeable while Win 7 is running. Expect windows apps to be slightly less responsive than when they're run in bootcamp alone. But if you have enough ram allocated its not an inconvenience unless you're trying to do some hard core gaming.
