Try this out...tweaked options (including the streaming). Axis takes 8 times slower consistently as compared to the ObjectOutputStream option. Memory has reduced too. Let me know if you see something screwy. I will try a bit more and report later. BUT am eager to hear from you.
I downloaded and ran your updated code, with a 32M max heap. It looks like it still takes more than 20M to serialize and deserialize a tree that takes less than a single megabyte in memory. It ran out of memory trying to serialize a 1844656 byte tree. Am I missing something here, or does this reflect the improvement you think your tweaks made?
Created tree with 5 levels and 3 children at each level
Total memory usage: Created tree = 905 KBytes (926744) Increase in allocation since last check = 905 KBytes (926744)
Total memory usage: Serialized tree = 5 MBytes (5737504) Increase in allocation since last check = 4 MBytes (4810760)
Total memory usage: Deserialized tree. = 18 MBytes (19448264) Increase in allocation since last check = 13 MBytes (13710760)
===========================================================
Created tree with 5 levels and 4 children at each level
