I have a mid-2010 MacBook Pro with the 2.66GHz i7 and 4GB RAM. I recently purchased VMWare Fusion 3.1 and installed Windows 7 Ultimate x64 and assigned it 2GB, leaving 2GB for OS X. To say performance was atrocious would be putting it mildly. Mouse clicks took 30 seconds or longer to register. I only had around 40MB free memory. So I reduced the Windows memory to 1GB and at first it was better, I had around 800MB free memory with VMWare running. To ensure optimal VMware Fusion performance, install as much RAM as you. Time(Mac OS X, Windows XP Pro and Windows 7) without major memory issues. But after about 15 minutes, available memory dropped to 70MB again. Is decent performance running VMWare impossible with 4GB of memory? I recently ordered 8GB of memory for this machine, I'm hoping that will help. I need to run multiple VM's of Windows (not at the same time) for work when traveling. I recently traveled for work carrying two laptops and it was not fun. ![]() Does anybody have experience of this kind with VMWare, and can recommend anything? Installed Windows 7 Ultimate x64 and assigned it 2GB Do you need the 64-bit version for some reason? 64 bit primarily becomes a factor if you're going to allocate 4GB or more RAM to the VM. Otherwise the 32-bit version would have a (slightly) better memory usage with 2GB. 2GB of RAM can be usable, depending on what apps you're running in the VM. For example, I run Win7pro 32-bit as VM with just 2GB of RAM allocated, but I only use it to run some small MSAccess programs and Crystal Reports. Avengers age of ultron download in hindi 720p. However if you're running something like Photoshop or Autocad, or need to have a several programs open at once, then maybe you do need more RAM. Win7 32-bit can just barely run with 1GB of RAM, if you don't have any other apps running. And don't forget that your antivirus program and such will suck up RAM as well, so 2GB is what I consider the minimum for Win7. Also, how many vCPUs do you have allocated to the VM? The general recommendation is to always start with 1 vCPU unless you have reason to need more. But even then, usually, you start with 1 then add more later. For more info, take a look at, about halfway down, the section on 'How Many Virtual Processors?' So start by leaving the VM with 2GB of RAM and reduce to 1 vCPU, if possible. Then if necessary, try tweaking the VM to 2.5 or even up to 3GB of RAM. While that's going to make OSX suffer a bit, if the VM works fine after that, you'll know that you need more RAM.
