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].
