function its (p) { return (navigator.userAgent.indexOf(p) != -1) };
if (its('MSIE') && its('Windows')) {
try { run() } catch (e) { get_a_Mac() }

A test of even standing the chance of being representative would not only
include a much greater variety of platforms, user agents and operating
systems, but also a great variety of hardware and software configurations
(for example, a sub-test with resource killing applications like Microsoft
Office running and one, under otherwise the same conditions, with such an
application not running).

Since it would be much too expensive, and ultimately futile to set up such a
test (because the results would be obsolete the day, maybe the hour, after)
just to satisfy the OP's curiosity, it should suffice to say that tables
should not have that many rows. Which is an opinion that can merely be
formed by applying common sense to this problem.
