MongoDB data with expiration date?

Question

MongoDB

I want to create documents with limited lifetime. My lifetime of this data will be equal to 5 days. I found special methods that do this in MongoDB. And I read in the documentation that once every 60 seconds. All documents are requested and the changes are applied. Because I want to do this for chat messages. There will be many such documents.
Question. How will this affect performance? Are there alternative exits? And if it somehow shakes the performance. Can I change the frequency of the cycle that is responsible for cleaning the data?
