in thread My data structure needs too much memory!

It would seem that either you are going to have to rework your algorithm or use a database.
Or use a language with less overhead. C or C++ come to mind. Or buy more memory. You should be able to get 12GB of RAM for about $1200 (with 4GB memory sticks). I paid more than that for a 486 with 4MB back in the day.
