How does the configuration about maximum locked-in-memory affect Couchbase?

Hi there,

I read document about deploy Couchbase on container at Couchbase.

The Increase ULIMIT in Production Deployments section has the sentence “These ulimit settings are necessary when running under heavy load”.
I really don’t understand how configuring ulimit -l unlimited will affect Couchbase if it runs under heavy load.
Hope to receive an explanation from you.

Thank you very much!

More (virtual) memory locked in physical memory results in less paging which results in faster performance.
