PROBLEM SUMMARY

USERS AFFECTED:
WebSphere Process Server and WebSphere
Enterprise Service Bus v6.1.0.1 users

PROBLEM DESCRIPTION:
The message processing capability of
WebSphere Process Server mediation is
found to have decreased when compared
with previous release. The performance
degradation is about 15%, both in
terms of processing speed and the
maximum message size allowed.

RECOMMENDATION:
None

The issue is due to extra debug trace added by the developer
during development phase. The debug trace has been hard coded,
and cannot be disabled by adjusting Service Component
Architecture (SCA) trace level. Neither was the debug code
removed prior to code check-in.

PROBLEM CONCLUSION:                                             
The error is corrected by removing the debug trace code. It     
have no negative impact on WPS problem diagnostic as the same   
information is logged elsewhere in the system when the Service  
Component Architecture (SCA) trace is enabled.
