same here. my motivation for this patch is to have a common tool
to measure ingress speed, so we can have concrete numbers to talk about.
Also, as you mentioned, there is always a danger of 'zooming in'.
Any type of benchmarking shouldn't be blindly followed. At the same time
all numbers are useful. They are different datapoints that make
a complete picture.
