Bit of an old thread but wanted to chip in with my experience as it may help others....
So I'm running Windows 7 Enterprise x86 (my corporate build) under Parallels 6.0.12090. I P2V'd my company laptop (Dell Latitude D420) which had a 1.2ghz CoreDuo CPU with 2.5GB RAM in it and a Harddisk that came from the ark - so the Macbook air virtual guest is MUCH faster. The guest machine is set to 2 CPUs, 2GB RAM, 60GB HDD, 256MB Graphics Ram.
I've got a Macbook Air 13" with 256GB SSD, 2.1GHZ CPU and 4GB RAM, Snow Leopard 10.6.8, usual Displayport to HDMI and VGA for presentations and Wired Ethernet for offices where there is no Wireless...
Key things I've found:
- Macbook Air has US keyboard even though its a UK model - so Win 7 has all the wrong keys assigned by default - I needed to change the layout to US in the Windows guest
- Under Coherence mode I cant find the taskbar pinned icons so I had to pin the same icons to the start menu
- Bridged Mode Wifi works fine at home but not in the clients site im on at the moment so I had to switch to Shared Mode (note System CPU utilisation goes up under Shared Mode for me)
- Mac Office 2011 apps are no where close to Office 2007 (Win) in terms of resource hog so I'm slowly trying to migrate over (although a whole bunch of missing features in Office 2011 Mac are causing me a world of pain)
- The CPU utilisation under Activity Monitor was always through the roof causing the fan to run at >3000rpm all of the time and the CPU temp to sit >80degC. To fix this I disabled graphics Vertical Sync, set the virtual HDD to be a fixed size and not compress, Disable shared folders (but left clipboard sharing enabled), set for guest performance to increase battery life, Mac performance preferred (not windows), Turn off adaptive hypervisor, Turn off Timemachine, Turn off snap shots, Turn off compress disks, Turn ON tune windows for speed. Now it hovers around 7-18% CPU utilisation and applications are MUCH faster.
- Disabled Bitlocker in the windows guest (My Mac's HDD has full encryption turned on which mitigates this)
Hope that helps someone
