I need some clarification regarding the transaction trace time in CA APM. As when i run transaction tracer in CA APM it display the details of transaction like methods,backend calls, webservices etc. In the details some times it shows the 0 ms time for some methods and backend calls. Now if any query is executed in the transaction so there should be some time but not 0ms.
Please guide me to understand that why this time is 0ms.
