# Thread Pool
+ Is there a bottleneck in the thread pool?
  + **`Raft store CPU:`** The `CPU` utilization of the raftstore thread. The `CPU` utilization should be less than **`80% x raftstore.store-pool-size`** in normal case
  + **`Async apply CPU:`** The `CPU` utilization of the async apply thread. The `CPU` utilization should be less than **`90% x raftstore.apply-pool-size`** in normal cases.
  + **`Scheduler worker CPU:`** The `CPU` utilization of the scheduler worker thread. The `CPU` utilization should be less than **`90% * storage.scheduler-worker-pool-size`** in normal cases
