We did a performance test with ContiPerf http://databene.org/contiperf and found performance degradation.
Test includes persisting and merging of POJO class without any associations. Attached are - 1) Entity class 2) Test cases
Below are the test results for multi-threaded tests-
with hibernate 4.3.5 :-
persist(test1) - 20000 invocations, 8 threads, rampup 1000ms - 42,381 ms
Throughput: 456 / s
Min. latency: 5 ms
Average latency: 16 ms
Median: 13 ms
90%: 23 ms
Max latency: 460 ms
select + merge (test2) - 20000 invocations, 8 threads, rampup 1000ms - 86,177 ms
Throughput: 232 / s
Min. latency: 7 ms
Average latency: 33 ms
Median: 29 ms
90%: 49 ms
Max latency: 535 ms
-----------------------------------------
with hibernate 3.6 :-
persist(test1) - 20000 invocations, 8 threads, rampup 1000ms - 32,442 ms
Throughput: 616 / s
Min. latency: 4 ms
Average latency: 11 ms
Median: 9 ms
90%: 15 ms
Max latency: 470 ms
select + merge(test2) - 20000 invocations, 8 threads, rampup 1000ms - 63,798 ms
Throughput: 313 / s
Min. latency: 6 ms
Average latency: 24 ms
Median: 19 ms
90%: 38 ms
Max latency: 535 ms
