Forgot to mention:
- this time it was Centos7.9.2009 (Core) with Linux mn10 3.10.0-1160.el7.x86_64

Perhaps older kernel describes poor master's performance on 2 sockets
compared to my previous results (when this server had Linux 5.10.103-1 Debian).

Or there is degradation in PostgreSQL's master branch between.
I'll try to check today.
