No official figure published for: minimum CPU cores, recommended CPU cores

The installation-requirements partial (rendered on the Linux/Docker/WAR/Windows/offline install pages) states RAM and drive space figures but never a CPU core count, minimum or recommended; the linked Hardware Recommendations page also discusses CPU only in prose, no core counts.

We publish nothing we can't source. Evidence of the gap.
