seriously, with optimisers it's becoming harder to make some measurements. C has a type modifier called "volatile" while forces true read/write on a variable, which can be useful when handling signals, threads, mmaped hardware, and... benchmarks.
That's very useful! Now I get a more sane result:
For SETFLOAT(a, i)
1e6 iterations: 5161 usec 1e9 iterations: 2.457 sec
Anyway... in the context of remote procedure calls and massive disk accesses, SETFLOAT should be the least of your concerns.
Agreed.
