# Conclusion (B)

+ Analysis conclusion:
  + tikv:
    + `raftstore.store-pool-size = 8` 
    + `raftstore.apply-pool-size = 2` 
  + The store pool generates pending apply tasks at a high rate, but since the apply-pool-size setting is still 2 (the default is 2), processing is slower on the apply pool side.

------------------------------------------------------------

Further confirm the parameter configuration of the cluster. Considering that the cluster is configured with store-pool-size = 8 (the default is 2), the store pool generates a pending apply task at a high speed, but since the apply-pool-size setting is still 2 (the default is 2), the application is applied The pool side is relatively slow to process, so it accumulates more or forms larger batches, increasing the delay of apply.
