Apologies for not replying sooner. I was pushing out the major website redesign.

I was seeing consistent 10-15% speed up when with depth-first. Your data seems to be supporting this to a degree too. Another thing was that NOT using FindExLargeFetch in warm-cache scenario results in 20-30% speed up (from 1000 ms to 800 ms). I added a command-line argument to control this in more recent versions of bvckup2-demo2.exe
I'd take the 80% median (sort and then trim 10% on each end) and then average it out. Also, as a bonus, if the standard deviation is high, then there's too much volatility and so the sample is not representative. With regards to visualizing, let me see what I can do. JS + Canvas might be the simplest option.
I think the key to unlocking this problem is called shutdown.exe :)

It would seem that the difference between depth- and breadth-first are pretty small for the warm-cache tests.

I guess the 16 consecutive runs should be processed into {min,max,avg,mean} values - should be easy enough to do the processing, but how to handle the rendering?

Also, if I find a way to automate the cold-cache testing (suggestions would be very welcome!)
