Did you dismiss them without checking if any in fact did show Java using 10-100x more memory?

You do seem to have dismissed them without asking yourself if they demonstrate the point you wish to make.

The obvious example would be binary-trees which mostly allocates and deallocates binary trees -

Java 6 -server #2 = 289,920 KB

Python CPython #6 = 674,488 KB

And if the Java program loops for 15 minutes -

Java 6 -server #2 = 855,996 KB

Does that look like 10-100x as much memory?
