    Description

      WiredTiger now has a phase at the beginning of checkpoints where eviction works to reduce the volume of dirty data to 5% of the cache size. In testing, some workloads experience a performance regression during this phase.

      Change the WiredTiger default to 15% to reduce the impact on such workloads.
