I think perhaps the problem with the on-one-line layout is that the grouping is wrong; grouping by unit probably doesn't make sense. So it makes sense to me to have: Sizes: psize=4/KB Transfer: total=16777992 kB transferred=37673019 kB remain=11563855 kB Pages: normal=9394288 zero=600672 Page rates: transferred=185875/s dirtied=278378/s Other: dirty_sync=3 postcopy_req=4078 so you have things on one line when you're comparing them - so it's easy to see the transferred page/s is way less than the dirtied in this example (really??) because they're next to each other.

Haha, yes; whatever it is for those humans find easiest - that's the H in HMP! (Those AIs can parse Json way easier than I can read Json!) Of course you don't need to reorg it all at once again, if someone finds one section hard, then reorg the way that people find it easy. > It's already in a pull, let's revisit whenever necessary.
