Abstract

OSP-PERFM MQM400-DELAY WHEN USING SSL WITH MQ V6

Error Description

There is a built-in delay for SSL processing with MQ V6 socket  
API's that causes performance issues.                          

Problem Summary

Switching the SSL on the SVRCONN channel leads to a degradation
in performance at the WMQ client; in terms of messages delivered
                                                               
Users Affected: iSeries users with SSL enabled SVRCONN channel  
                                                               
Platforms Affected: iSeries                                    
                                                               
Investigations revealed that there was a possibility of a      
quarter second delay while retrieving the SSL records          

Problem Conclusion

Code changes are carried to avoid identified delays which will  
improve the performance
