Would it be possible to convert the data structures used to ones that are less memory-consuming? For example, I know you use hashrefs. What about using arrayrefs and constants for the indices? That should reduce memory usage by about 15%. Also, you could move to an inside-out objects type of structure, which would help even more here because you have lots of little structures.

I shouldn't have to say this, but any code, unless otherwise stated, is untested
