I was wondering that too, but there aren't that many common cloud provider that has 96 vCPU offering.

I am also wondering on 144 Workers, on 96 vCPU which is not 96 CPU Core but 96 CPU thread. So effectively 144 Workers on 48 CPU Core possibly running at sub 3Ghz Clock Speed. But it seems they got it to work out in the end. ( May be at the expense of latency )

Assuming you're running a system where normal request/response handling blocks on database queries it's often optimal to have more workers than available cpu threads and 1.5x is a common rule of thumb to try first.
