When was this? I've been using IDEA for years and I've been satisfied with memory usage. There's actually a problem with massively increasing the memory usage such that more and more garbage builds up making garbage collection take much longer and causing freezes, though newer GC does much better here.

Also keep in mind what IDEA is doing with that memory. It's storing indexes to all your code and libraries for near instant bidirectional navigation and search.

Also be weary of supposed high memory usage with Java. The JVM will allocate memory from the operating system for the application but then not actually use it. It's doing this so that in the event the memory is needed, it's already been allocated to the process. I've seen other apps increase the overall memory load and the JVM then relinquish it's pre-allocated-but-unused memory.
