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). Regards, Radek
