Performance issues with WebLogic Tuxedo Connector(also known as WTC) on WebLogic 12.1.3. This is not observed in WebLogic 12.1.1.
Investigating found that method isTightlyCoupledTransactionsEnabled() in TCResourceHelper, called by getTuxedoConnection in TuxedoConnectionFactory, creates a JMX connection to the WebLogic AdminServer for each call.
This severely degrades the performance of WTC, by several orders of magnitude. One service takes ~2ms on 12.1.1 and on 12.1.3 it takes ~49ms.
