Good to know, We haven't upgraded to 9.6 yet, however, but I'll suggest that for this upgrade.

One of my system admins has approached me about replacing our production data warehouse system. I believe I know the answer, but would just like more opinions. He's giving me two options so far:
1) CPU = Intel e5-2637 3.5GHz 4 core with hyperthreading
vs.
2) CPU = Intel e5-2650v4 2.2GHz 14 core with hyperthreading
The rest of the specs are identical with 512Gb RAM and more than 2 Tb SSD drives. Our data warehouse is just shy of 2Tb now. I suspect the the first option would be more optimal as I don't think PostgreSQL can make effective use of a lot of processor cores. So fewer cores would be better optimized with the O/S. Can anyone weigh in on whether my assumptions are correct? --
