Yes, you're probably right that no respectable database is going to have a problem with lock contention on 16 cores. But, AMD released 12 core processors this week. Its likely we'll see the average DB server have 48 cores sometime in the next year or two, and who knows after that.
- cperciva 17y agoI quoted 16 cores because that's the biggest hardware the FreeBSD project had available when those benchmarks were being run -- I suspect that it scales linearly quite a bit further than that.
