Dear all,
By my test, the performance down greatly than the test case without the transaction. For same program: Without transaction in Session, 1000 tps; With transaction in Session, about 10~20 tps which is absolutely my expectation!!!! I attached my source files and configuration files. It's much appreciated if any suggestion. Thanks a lot!
