Reason Visual Studio would be slower on 64-bit dual core machine? [closed]

Scenario: Visual Studio 2008 (version 9) is installed on two machines:

• a desktop machine: 512 MB RAM, 1.4 GHz CPU, Windows XP (Service Pack unknown).
• a new laptop 4 GB RAM, dual 2.1 GHz CPU, 64-bit CPU, Windows 7.

While running a web project, loading/debugging and then navigating to page takes approx. < 1 second. On the laptop machine, the same actions take more than 3 seconds (sometimes ~ 2.8 seconds).

Question: What might cause the compilation and loading of the same VS project to be slower on the new machine? Are there settings I can tweak to make it more suitable for my computer?

-edit- i notice the answer link isnt valid. The problem had to do with ip6 and setting network.dns.disableIPv6 on firefox to true

I'd look at the speed of the hard-drives as the possible limiting factor. Most laptops have 5200 RPM drives, a 7400 RPM drive can easily outperform it.
