A system and method for providing dynamic transaction optimizations, such as dynamic XA transaction optimizations. In accordance with an embodiment, the system enables monitoring of transactional behavior in an application during runtime, in order to provide a feedback loop. The application/transaction information in the feedback loop can be analyzed by a transaction manager to determine an indication as to whether a particular optimization, such as an isSameRM optimization, will provide a benefit or not. The optimization can then be applied accordingly. In accordance with various embodiments, such determination can be made transparently, so that its enablement is not detectable to, e.g., an end-application, or a system administrator, even though the distribution and type of XA calls may be detected through system monitoring. The feature can be used to improve the performance of transaction processing in a transaction-based system.
