APAR PQ71127 addresses the following performance issues that
result when recording Web Container SMF data:

1) When Web Container records are recorded, J2EE container
records are also recorded because the Web Container is managed
as an EJB. These duplicate records should be eliminated.

2) Constant Strings are translated to byte arrays multiple
times.
Problem conclusion
The following Web Container SMF data recording performance
issues have been addressed by APAR PQ71127:

1) Support has been provided to eliminated duplicate Web
Container SMF data records.

2) Support have been modified to cached byte arrays, thus
eliminating multiple translations.

APAR PQ71127 is associated with SERVICE LEVEL W401504 of
WebSphere Application Server version 4.0.1 for z/OS and OS/390.
