is it possible to reduce the mongodb memory usage


is it possible to reduce the mongodb memory usage  using -'mongodb'

I am undergoing testing with 64-bit MongoDB. If I configure large size backups then the MongoDB memory utilization seems to be high.

Is there any possibility to reduce the memory utilization by MongoDB.

For Windows it seems possible to control the amount of memory MongoDB uses, see this tutorial at Captain Codeman:

Update /etc/security/limits.conf

Add a line as below:

@mongodb - rss 33554432

and then save the file.

It will take effects right away.

In this example, we assign 32GB memory usage for mongodb group users

Do you mean memory usage or disk space? If you are really talking about memory, then Mongo stores its data in memory-mapped files, giving the illusion of massive memory usage.
