When do you need to analyze MongoDB performance?
MongoDB Performance ¶ As you develop and operate applications with MongoDB, you may need to analyze the performance of the application and its database. When you encounter degraded performance, it is often a function of database access strategies, hardware availability, and the number of open database connections.
Why are write operations so slow in MongoDB?
The capability of the storage system creates some important physical limits for the performance of MongoDB’s write operations. Many unique factors related to the storage system of the drive affect write performance, including random access patterns, disk caches, disk readahead and RAID configurations.
What’s the maximum number of writes in MongoDB?
Changed in version 3.6: The limit raises from 1,000 to 100,000 writes. This limit also applies to legacy OP_INSERT messages. The Bulk() operations in the mongo shell and comparable methods in the drivers do not have this limit.
