Hrm, I think this might depend on what you’re solving for. This is the
conventional wisdom for MDS for sure. My sense is that OSDs can use multiple
cores fairly well, so I might look at the cores
AFAIK the standing recommendation for all flash setups is to prefer fewer
but faster cores, so something like a 75F3 might be yielding better latency.
Plus you probably want to experiment with partitioning the NVMEs and
running multiple OSDs per drive - either 2 or 4.

Indeed, I know from experience that LFF spinners don't cut it
