Why is mongodb’s insertion so unstable

 May 12, 2019   mongodb, question

I initialized a 1000w fragment set, and then inserted 10w data into this set. The speed was extremely unstable during the insertion process. Even one data insertion was performed for more than 1 s. What is the reason?

Forgot to build the shard index key, check it.
