Hi 18621325186@163.com, are you still experiencing issues here? If so I'd like to suggest upgrading to our latest 4.0 maintenance release, 4.0.27. If the problem still occurs on that version we can dig in further. |

Hi, Eric Thank you for you replay ! If you analyic the case carefully , you will find the slow logs only be logged on mongos . I think the slow queries weren't be only happened on the mongos and weren be logged on the mongod's log files(and the queries with shard key should be excuted quickly). Gratefully |

For this issue, I'd like to ask that you start with our community by posting on the MongoDB Developer Community Forums. The SERVER project is for reporting bugs in the MongoDB server, and the presence of logged slow queries isn't by itself considered a bug. If the discussion there in the community forums leads you to suspect a bug in MongoDB, that's something we'd want to look into here. Gratefully, |
