In case people want to give this setting a try, here is what to do.

On 2-nodes EP:
# echo 2 > /sys/devices/virtual/workqueue/batch_free_wq/max_active
# echo 1030 > /sys/kernel/debug/parallel_free/max_gather_batch_count

On 4-nodes EX:
# echo 4 > /sys/devices/virtual/workqueue/batch_free_wq/max_active
# echo 1030 > /sys/kernel/debug/parallel_free/max_gather_batch_count
