Re:hinit?

Thank You for answer ( sorry but i couldn't write
earlier ). It explain me many things but i steel
receive the same results:

1)Program which  uses the same registers one by one
works 
4% faster then when it uses different.

I received this by 'time' command. It shows that
program using only registers is about 16% slower then
exchanging with memory. "Program" moves values 2^29
times.( is there any way to check duration of program
with less then 0.001s accuracy ? any clock in bios ? )

Any way i'm steel looking for some hints that could
make my programs work faster :).
