I think we can all agree that the code above shouldn't take over 3 seconds longer to process in 6.17, that's a 3118% increase (yes, over three thousand percent longer).
It shouldn't take over 3 secs longer, and it doesn't, at least on my computer. For 200 iterations, there is hardly a measurable difference here. So I changed 200 to 5000 in your snippet and I noticed that 6.16 takes around 4100 msecs while 6.17 takes around 4300 msecs to finish. These results seem to agree with my original findings. What's for sure is that there's no 3000% increase in running time or anything of the sort: I only got a 5% increase.
