Hi! "After I reduced the checkpointFrequency, the block time decrease to 10 seconds." Good news!
"But I do not understand how the checkpointFrequency impacts the partition map exchange, can someone explain it?" Applying chages from WAL since last checkpoint (i.e. recovery) is a part of PME proccess. So, the more often checkpoint the less changes will be applied from WAL. You could find more information about checkopointing here [1].
