Yeah CockroachDB suffers from the same problem as PG: the defaults kinda suck for certain workloads. CockroachDB has an additional problem that their documentation isn't as detailed as PG so it can be hard to know what to tune. TiDB and Spanner defaults are much better for a wider range of workloads.

Can you say more about workloads which suck for either of the two databases at their default settings?
