Problem

After a migration from API Gateway 7.4.0 to 7.5.3 "Send to JMS" as well as 'Read from JMS" filter took 8 sec than 0.5 sec (7.4.0).

Resolution

- removing 'dhbcore.jar' from /ext/lib brought a processing time of 0.6 sec

- removing 'javax.net.debug=all' from the /instance/conf folder brought a processing time of 0.3 sec.

Recommendation: grep recursively for 'javax.net.debug=all' to whole /apigateway folder for similar settings - to be removed.
