I am using the pre-compiled, downloadable castor-0.9.3
version. I've made some tests with JDO on small object updates / queries /
deletes testing single transaction speed. Comparing the results with the same amount of data transfer
directly using JDBC (therefore eliminating the object<->table mapping
overhead and simply executing insert / delete / select SQL commands), I've
measured about 30 times more performance.
Unfortunately I cannot avoid using one update / delete /
query per transaction, which I know is slow.
I'd like to know if there is something I could do
about reducing this overhead of JDO, e.g. by compilation parameters, preference
settings or other ?
Thanks,
Norbert
