yes

you mean the peformance issue?

I think this depends very much about the context, how the groups are 
being nested and how often one is calling this method.

In what context are you using it or rather what do you try to accomplish?

See the javadoc at

src/core/java/org/wyona/security/core/api/User.java#getGroupIDs(boolean)

You might also have a look at

src/util/java/org/wyona/security/util/GroupUtil.java#getGroupIDs(Group, 
boolean)
