   Why would you only care about that, though?
What if you have a C# program that just doing
something like FTP? It takes seconds to get off
the ground, loads hundreds of MB of slop, then
has to call into the framework to access the
system DLLs. (It can use native code, but that's
another issue.) All that to make a couple of calls
to a server and download a file, which will be done
through a bulky series of wrappers.

  That's a real world scenario. If you're writing software
that does something like sharpening routines on
large images then the math speed will be critical.
But otherwise it's like saying your Ford Focus rolls
downhill as fast as a Ferrari. Sure. But how long did
it take to get up the hill?
