The CEM Business transaction screen opens slowly. This did not happen in APM 10.5 , only 10.7 SP3.
Release: APM 10.7
Component: APM 10.7
Too many transaction discovery definitions on the business transaction screen.
Issue was not a 10.7 SP3 issue. 10.5.2 system had few business transactions. Deleting the transaction discovery definitions made it open in seconds not minutes.
