I must add another reply to this:
To all you guys who could not read about what this topic was about, and tried to explain the sluggishness of the Management console with an underpowered disk configuration:
It is because the console use a JIT compiler to build machine code out of a higher level language.

No wonder, it takes ages until the program finally can launch. This Design has most likely a much larger footprint, and, if, must be compiled at runtime will hog the CPU and never can be as responsive as a "real" program.
Look at Java (or, at your blackberry).
I do not want to say this kind of design is good or bad. Depending on the purpose it can make sense. The performance penalty will also be less if using a better CPU or Disk subsystem. But it can never reach the launch time and execution speed of a compiled program.
And it explains the difference compared to Exchange 2000 or 2003 perfect.
