From Admin Guide under section 36.6.1 Back End Tuning Parameters

"je.checkpointer.highPriority

If true, the checkpointer uses more resources to complete the checkpoint in a shorter time interval. Btree latches are held and other threads are blocked for a longer period. Log cleaner record migration is performed by cleaner threads instead of lazily during eviction and checkpoints (see CLEANER_LAZY_MIGRATION). When set to true, application response time may be longer during a checkpoint, and more cleaner threads may be required to maintain the configured log utilization.

Setting that property to false is a way to achieve better throughput and lower response times.
