You need to use a profiler. You can try an evaluation version of
YourKit for example. It has a nice Eclipse plugin, so you can profile
straight from Eclipse:

(wonder if ASF has a free open source license for YourKit?
ObjectStyle does - it was granted to Cayenne project in the past).
I think we can probably optimize ID Map creation by storing the
values in an Object[] instead of a Map, but we do profile data to
tell whether it is even a bottleneck (and not the ResultSet reading
for instance).
