It was my impression that these patches were much about improving
overall tps and more about reducing latency spikes for specific
transactions that get hit by a checkpoint happening at a bad time.

Are there any reductions in max latency for these pgbench runs..?
Assuming that's information you can get..

Thanks,

Stephen
