	Well, it really depends on the way you program in asm ! If your asm 
   programs are only 5% faster than your C ones, then forget about asm. But 
   if you need speed (the main reason you write part of your code in asm 
   usually), and if you know about good asm programming then you can use asm 
   and it will be more than 5% faster than C.

Yeah, if you're only getting 5% out of recoding in asm, you're
probably doing something wrong. In the right circumstances, you can
buy almost a factor of 10 more speed out of asm.

Of course, if you did it right in the first place, and went to a good
CS reference library instead of the asm manual, you'd realize that the
factor of 10 is the bare beginnings of what you can do. Instead of
talking about 10 times as fast, you talk about n-squared as fast. And
you can still code in something where you don't have to worry about
the trivia.
