The answer is "may not be." Imagine some syscall that's slower on operating
system A than it is on operating system B. It's of course possible to
construct an app on system A that uses this syscall so many times that the
syscall's contribution to response time dominates the user's experience with
the app.

I think Billy's point is that the odds of this happening to you are slim,
and I think Leandro's point is that the odds may be higher than you might
believe.

I'd like to insert the perspective, "Why bank on 'odds?'" No matter what the
odds, it might be affecting you; it might not. If you learn how to measure
response time accurately, then you'll KNOW whether you're affected, and
you'll be able to make an informed decision about what to do next.

If you learn how to measure response time accurately, you won't waste your
time fixing things that aren't problems, and you won't have to endure
problems that you can't detect.

        Is not or may not be?

        If a particular OS is of bad quality, and moreover if it
participates in a culture of low quality, chances are it will have bad
performing parts and components one depends on will be badly implemented.
It will even tend to have lower quality sysadmins with bad information --
specially if it's a black box.

        OK, but that does not preclude the possibility of a specific
application depending on something that was badly implemented in a
particular OS.  And if that particular OS already makes part in a
low-quality culture, the chances of hitting particularly badly implemented
components in the platform is quite high.
