Is there ever reason to think the >> (signed) and >>> (unsigned) right bit-shift operators in Java would perform differently? I can't detect any difference on my machine.

This is purely an academic question; it's never going to be the bottleneck I'm sure. I know: it's best to write what you mean foremost; use >> for division by 2, for example.

I assume it comes down to which architectures have which operations implemented as an instruction.

Hi all, I discovered something odd that I can't explain. If someone here can see what or why this is happening I'd like to know.
