I'd suggest just loading up some dummy data in a medium-size table and
seeing if you can reproduce the variance in index build time. It's
unlikely that you need a ten-hour test case for that. But there may
be some small detail of what you're doing that is necessary to show
the problem, so I'm not going to try to reproduce it here with no
concrete example to go on.
