JDO uses a StateManager interface to read/write field values and so avoids any reflection overheads which might affect other products.
Kodo JDO is an efficient and highly optimized JDO implementation which exploits the features of the underlying database as far as possible to optimize performance.
Kodo is currently one of the two JDO implementations which are tied for best place in The Middleware COmpany's TORPEDO benchmark, which tracks hits to the database as an indication of efficiency. See http://middlewareresearch.com/torpedo/results.jsp.
