Or open a command window and type in the command line as I did (see 
attached screen grab).

If you are on the system console of a Windows 7 box, you can right click 
on the system icon and pick 'Properties', then click 'Performance 
Information and Tools' to get to a "Windows Experience Index" screen.  
Unfortunately this refuses to run over an RDP (remote desktop) 
connection, so it is back to the command line for me.

Yes it would be interesting to hear about SSD.  Your numbers are about 
as bad as on my laptop, a Dell E6420 loaded with AV and other corporate 
mandated S/W.

That is internal corporate trivia, so I will tell you about it off-list.

Not much - at least I have not noticed it.  You typically pay once for 
the time to fetch or update the sources, and then build many times.  
That is why we want everything local to the build system.
