Quick supplement on that: actually there is a way to let single
crimson-osd instance to span multiple CPU cores while preserving
the shared-nothing design. Definitely the doors for it should be
kept open but – as it requires an extension to the RADOS
protocol – it would be preferred to not hurry up. IMHO we should
consider it after the seastore (BTW: persistent object store is
worth ~200 kcycles / op accordingly to Mark's testing).
