Here is the combination of settings that seems to have resolved my issues now. The other week I decided enough was enough, and spent a bit of time googling and looking around the VMware Communities forums for a fix. Most of the time just restarting the Windows VM itself would not help though – I would have to reboot the whole macbook. I knew it was the VM though, as everything in OSX Mavericks, the host OS was perfectly normal. Nothing seemed to fix the performance issues I was seeing, which was that by at least half way though a typical work day of using Visual Studio and a few tabs of Chrome/IE/Firefox, the VM would slow down to an absolute crawl. This VM is running on the built-in 256GB SSD. I have a Windows 7 Professional VM running in VMware Fusion, with a spec that I had tried all kinds of different configurations on – mainly 2 vCPUs, and 4GB RAM though.
I have the following specifications on my Macbook Pro Retina which I use for development purposes: I just didn’t get the time to dedicate to find a fix for the performance degradation I was seeing until just recently. I have been struggling along with various VM performance issues over the last couple of months using VMware Fusion 5.x, as well as the latest 6.0.3.
