I would like to see the time for each run (if 10 runs, then 10 columns
i.e., xx_run1, xx_run2, ...), rather than only average of them.

Collect as much as insights we could, maybe we find some pattern or
something that might help us (not sure what though). Since I have a
feeling, we might get better performance in one run and not so good in

I notice that some ports take less time with modification and some
ports take more time. Just want to make sure it happens in multiple

In an ideal scenario, I would prefer a clean environment (can be a
fresh install of OS, bare minimum apps running, reboot before each
run, etc.) to run each test (containers maybe? or some CI like travis)
which might not be affected by other processes running in background.
