Performance of Virtual Machine

I gave up dual boot when I upgraded to Ubuntu 11.04 and moved Windows into virtual machine. The performance of Windows guest was good, 35 seconds from power on to desktop (very good as my HDD is 5400 rpm), until I began using it seriously.

I've done a benchmark of compiling one of my GWT project in Eclipse four times. I still remember Turbo C can compile 10 lines of code per second, while Turbo Pascal can compile 100 lines per second when I was in university. Compilation is quite suitable for benchmark because it involves both CPU and I/O tasks.

The Windows I'm using in virtual machines is Windows 7 Professional 32-bit. IDE is Eclipse for Java EE 3.6.2 32-bit for Linux and Windows. Virtual machine software are Oracle VirtualBox 4.0.8 and VMware Player 3.1.4, for Linux of course.

This is by no means a scientific benchmark, but what I got is if you plan to use a Windows guest heavily in a Linux host, VMware Player is the one to go with at the moment.
