MongoDB regularly releases memory

For databases that are mainly written, the write efficiency becomes unstable when the MongoDB memory is full.

At this time, you need to release the memory (you can try dB. runcommand ({closealldatabases: 1 }).

The following C #CodeIt can be used to release memory on a regular basis. When using it, replace the path with the path of your server, and modify the release frequency.
