The thing is, we aren't trying to "scientifically correct" statistics. What we're aiming to say is, "This is not so wildly different as to be of any concern." We aren't looking for minor difference, but orders of magnitude difference.
If you are that worried about a <2% difference in speed, you probably shouldn't be using Python... or at least Django. You should be finding the parts that you can optimize for your specific application and optimizing those. Python 3 *IS* the future. There isn't much way around that at this point. I believe the general idea is to make sure the solution at this point does not slow everything down to the point where it would be impossible for someone to switch to Python 3. Don't get me wrong, I don't want to see a 2% increase in timing all the time, but Python 3 support is a bullet that will HAVE to get bitten. Also, I am expecting I could make bigger gains by just using that pure Python MySQL driver and running under PyPy. If the major part of the time wasn't spent inside the actual database (which should be fairly obviously the case as switching from SQLite in memory to MySQL is a >5x increase in time).
