  1. Yes I figured that out once I examined the data. But ony after it was uploaded. When I ran armbianmonitor though I did not expect it to do automatic upload and my immediate reaction was WTF
  2. That's kinda obvious, as all 3 share the very same on chip ethernet port. But I'm still struggling to understand how come my T4 is running 4.4.192 just fine, but neo4 is experiencing a massive packet loss running 4.4.208 and one of the earlier 4.4.x versions but 5.4.20 and 5.3.x before - all good. So now on that automated testing script topic: is it to be run as root or a regular user? Is it safe to run on a live system? Does it send anything automatically like armbianmonitor does? (To be honest - I was unpleasantly surprized seeing the data collected sent somewhere without review
  3. I'll definitely look into it now, seems neo4 is not quite popular out there, I must be one of a few 'lucky' ones :)))
  4. Great observation, thank you Werner! Before the upgrade from Stretch (was not Bionic, sorry, my mistake) I was indeed running kernel v.5.x because back then I also saw some slow performance but blamed it on a new USB enclosure without proper testing, then just upgraded the kernel and that solved the problem. In fact I bet it was the very same thing. Now after switching to 5.4.20 theres still some insignificant packet loss but guess I can live with it.
  5. It's not an 'upgrade' per se, rather a clean install.
