I haven't looked into Apache commons-primitives. Before these available, we made use of Colt libraries map features:
They made a huge difference in the GC time. I would say yes, it was definitely worth the effort.

By the way, we use lists of integers, maps to and from integers, maps to
doubles, all over the code, and in some performance-critical areas. Java
autoboxing makes it easy to forget that every access to these structures
involves converting a primitive type to an object, often allocating an
object for the purpose.
I've been thinking of using apache commons-primitives for these structures.
primitives/IntList.html for instance.) Anyone have any experience with these
classes? Is it worth the effort?
