I created a Windows 7 Enterprise 32-bit VM and a 64-bit VM. I wanted to see which provides better performance. Since VMware Tools aren’t ready I treaded lightly with my tests. Other caveats: VMware Fusion does not support Windows 7 yet. These are PassMark tests and not real world tests. I didn’t run endless tests – just a handful. Your milage may vary (greatly!). The performance is based on Win7 32-bit (32/32). The results are:
Win7 64-bit Running PassMark 65-bit (64/64)
29% faster on CPU
178% faster on 2D graphics
36% faster on Memory
19% slower on disk operations
Win7 64-bit Running PassMark 32-bit (64/32)
11% faster on CPU
13% faster on 2D graphics
11% faster on Memory
35% faster on disk operations
I was perplexed on the 64/64 disk performance being slower than the baseline and re-ran the test a handful of times and got similar results. 64/64 2D graphic results were impressive but not a driving factor for me. For CPU and Memory 64/64 showed a nice bump over 32/32 and even 64/32. In the end, the issue of whether to move to 64-bit Windows 7 is moot for me – the driver I need is only available in 32-bit so I’ll be running 32/32.
Here are all the versions used in the testing:
VMware Fusion Version 2.0.5 (173382)
Microsoft Windows 7 Enterprise [Version 6.1.7600]
VMware Tools for Windows Version 7.9.6. build-173382
PassMark PerformanceTest 6.1 (1010) WIN32
PassMark PerformanceTest 6.1 (1018) WIN64
After installing a couple of Mac OS X 10.5.6 Software Updates today:
- Security Update 2009-001
- Java for Mac OS X 10.5 Update 3
I received “The network bridge on device /dev/vmnet0 is not running.” error in VMware Fusion v2.0.2 (147997) when I tried to restore my Fedora 10 VM. The Google search produced some interesting results but nothing worked. I reinstalled Fusion and the dialog went away but network bridging still did not work. I then uninstalled and then installed Fusion and the same result. I rebooted my XP VM and it doesn’t have network connectivity either.
What finally did work was to uninstall Fusion and follow the manual uninstall procedures here. Then after a clean install network bridging is working again.
