Update on I am a bit worried about Pink system requirements
The very excellent Ben Williams and Nico Meisenzahl have dug deeper in Orient Me and found ways to reduce the footprint.
See their blog posts here and here.
I now have Orient Me running with 4 cores. I understand this is not a supported configuration, not until IBM comes up with a way to downsize Orient Me to less than 8 cores, but is definitely a big step forward.
Thanks Ben and Nico !
