Hello Guys,

We are facing one issue on PRODUCTION Environment, trying to import Groups from LDAP. Everything is working fine except the CPU Usage issue.

When the LDAP Import is trying to start the Group it goes to the CPU Usage of 200%+.

I found that in LDAP there is one Group in which there are 15k users.

And after digging in the code, I found that PortalLDAPImporterImpl.java



So, it was taking all the uerId(15K) in one Array newUserIds and trying to add. So it was taking much time and also increasing the CPU Usage at this place.

If any one faced same problem then plz suggest the alternative for this.

Well, unfortunately I think you're stuck with it due to the size of the group.

The good news is that the creation of the 15k users would only occur once during the initial import.

The bad news is that with import enabled, Liferay will continue to pull the group and verify that the users exist and are still members of the group, so it's going to chug through those 15k users every time.

Thanks David for the Response.

Is there any way to deal with it ?

I am thinking that instead of adding all the 15k users at a single time in group. Can I make it in bunch of 500 users and run the for loop in order to add 15k users.

Is it efficient way to do it and also one more thing, will it make difference to the CPU Usage?

Your issue is the size of the ldap group. Liferay's still going to attempt to synchronize it regardless of how you create the 15k users. Besides, doing it yourself may only lead to problems rather than solutions.
