I have boot camp partition running Win7 that I access through Parallels 8 running the latest release. I'm having horribly through put on my network with parallels. Running speed test on Win7 Machine: Down: 16.18 Mbps Up: 0.52 Mbps Running the same test on the Host Mac while everything is still up and running: Down: 13.06 Mbps Up 13.66 Mbps These machines are running on our work network, through the Thunderbolt to giga-bit adapter. My Win7 network settings are set to Default Adapter (need separate IP for testing IIS) I have tried switching over to shared to see if that would change my performance, but the performance is the same. Any thoughts would be greatly appreciated. Make it hard to support my clients when I am uploading 42 meg worth of code changes at 6 - 12 k a second.
