Hi Kyle, you reminded me of something. Perhaps some other people could comment on this, too.
The setting i currently use is -Xms32 -Xmx128 for setting my preffered min and max heap sizes. -Xincgc acitvates incremental garbage collection. I simply don't quite know what i it does to the VM, but i encountered better memory management. It seems that the VM always tries to release its free memory back to the system. One can monitor a free VM memory of 1 to 2 MByte, always. For my app it's definitly a recommended VM setting!!
