It seems to me that it would be simple enough to write a script to do
that to avoid any other noise: allocate an array with N random
elements, and fetch the M-th element from it after applying a sort
method. I highly doubt that you'd see much difference with a low
number of elements, now if you scale at a thousand standbys in a
quorum set you may surely see something :*)
Anybody willing to try out?
