Hey, sorry for the late response, just returned from PTO
The controller is deployed on an Ubuntu VM running in an EC2 instance in AWS. Some days prior to trying the upgrade I took a snapshot in AWS of the whole EC2 instance and that was what I used for the rollback.
However, not everything came back perfectly. I am getting some random issues with the GUI console that did not happen before.
But the main issue is that the performance issue is still happening. I can see easily replicate the issue that I explained here: Question about terminator - #30 by Foles_90 and I need to try that upgrade to see if this fixes it.
