#16954 was a major blocker in being able to increase the default range size from 64 MiB (another potential problem is #22348). Since #16954 has been closed, we can experiment with larger default range sizes.

I ran tpcc on a 3 node cluster with 16 vCPUs, 2500 warehouses, and an average range size of 500 MiB and a max range size of 1 GiB and nothing seemed to blow up.

There were a couple of latency spikes during the ramp-up period of tpcc, but I think they were caused by the destruction of old replicas when the initial splits were merged from setting up the workload (not too sure about this).
