Huh! Do you have any online numbers for that cluster?

And, if you can do a Postgres meetup in the Bay Area, I think we'd be interested ...

I suspect that unless you have 10GbE for your ceph storage network running any sort of RDBS on it is going to be pretty painful.

We do 40GbE end-to-end, so we peek out around ~4.5 GByte/sec of "disk" I/O.

I'll go rerun our benchmarks, my notes here say "~6000 tps", but doesn't include the parameters for filesystem or versions, nor which transaction is actually benchmarked. My bad for not taking proper notes.

We'd love to present this at the PostgreSQL meetup; what's the best way to get that going?
