I would mandate the 10-25% test no mater what language is being used. 

The bulk of programming is done for Finance, Insurance and Real Estate (and 
is done in COBOL </yuck>) The most common programs out there are OSs and 
MS Office. As I said, I don't care about games.

well that's also a way to make it run faster.

Clearly you can't cut core features, but you can make some eye candy features 
go away when there isn't enough power to run them.

If a different design is practical and would be faster, you should have used 
it in the first place or should be planning on doing it at some point anyway 
(I have never seen a non trivial program that was fast enough that I didn't 
whish it was faster).

I will grant that games can legitimately require top of the line hardware 
(scientific programs, and some things like photoshop can also) but most anything 
that runs on a desktop should be written so that people can run it with the 
hardware they have now, rather than have to buy new hardware
