I'm trying to run with -Xmx512m but the test runs out of memory during the delete. The attachment also contains an update test which has similar memory problems. I'm running both tests with the default objectdb.conf. In general is an UPDATE/DELETE statement the most efficient way to update/remove a large number of objects? ... a larger heap size.
