> Let's prototype the best possible scenario for how well we can perform with a thread per core design by simplifying everything we can.  For instance,
> - No HH, no RR, no replication at all
> - No MessagingService
> - No compaction (so test a workload w/o overwrites)
> - No repair
> - Just local writes and reads
> If we can't get a big win (say at least 2x) with these simplifications then I think we can say that it's not worth it.
> If we can get a big win, then we can either refine the prototype to make it more realistic or start working on it in earnest.
