13" MacBook Pro is not a performance machine, the higher end 15" and 17" are with their powerful dedicated graphics and quad cores.
Fresh installs of Windows requires a day or so for the validation to work through, then you get the updates and performance.
Windows needs 2 cores and 2-3GB of RAM all to itself. So for virtual machines you can really only use half of your RAM and cores, unless you want major OS X peroformance issues.
I am experiencing similar symptoms to those described above; Mar11 15" MBP, which boots really fast and apps open quickly too. Performance slowed after installing Win7 (not having much luck with VirtualBox- several windows programs I want to use dont work, so using boot camp).
The general slowdown and "disk thrashing" mentioned seems to be stopped by preventing spotlight from indexing the bootcamp partition.
@ds store - I am interested in your comment "Windows requires a day or so for the validation to work through"- you dont mean that this will affect the machine when booted into OS X, I assume? I have installed all the (seemingly endless!) updates (including SP1), but not yet validated my Windows install. Windows performance seems pretty good to me.
Upgrading to Mac OS X 10.6.7+ fixed the problem. I've used windows and mac multiple times, not noticing any performance issues. Not on Mac, atleast, which is my main. I've upgraded to Lion, but haven't tried Windows on Bootcamp after upgrading yet. I don't think it'll affect the performance of Windows, though.
i am an imac user and have been using bootcamp for a while. it has not slowed down any of my process.
the reason for your system to respond like this is.
1. your mac configurations are a bit low to support 2 OS'.
2. according to the installation guide a mac OS x higher or equal to 10.6.7 is required, which in your case might not be satisfied.
Thanks! I had simliar issues of sluggish apps and loading etc...after I installed Windows 8.1. I did what you mentioned RE spotlight and BAM, totally different. So, this worked for me.
15-inch, Mid 2012
Processor: 2.3 GHz Intel Core i7
Memory: 8 GB 1600 MHz DDR3
Graphics: Intel HD Graphics 4000 384 MB
Software: OS X 10.8.5 (12F45)
I had these problems too when I used bootcamp to install Win7 64 bit onto my macbook air 11" i5 mid 2013. In preparation I switched on Time Machine and connected an external drive to back up which was great and caused no issues. I ejected the drive but left time machine switched on and proceeded to use Bootcamp and install Win 7. Everything worked well but then I noticed when I switched back to my mac book air, OS X mavericks was running very slow. Eventually, I worked out that Time machine was still switched on with no external drive connected! As soon as I went to the time machine APP and switched it off, my mac sprang back to life! Everything now works really fast again on either Win 7 or OS X mavericks! I hope this helps anyone who is experiencing this problem.
