IBM AS/400e

Workload and Performance
34 AS/400e System Handbook
– Any system administration job submitted to batch is not considered interactive work.
– Any use of Operations Navigator (GUI administration functions) is not considered
interactive work.
• Interactive workloads: Any task started through a 5250 session (5250 device or 5250
emulation) where the user waits for a response is considered to be AS/400 interactive
work.
– Application processing that uses 5250 interfaces is not supported on the AS/400e
Dedicated server for Domino.
– 5250 print is not supported on the AS/400e Dedicated server for Domino.
Relative performance measurements are derived by performing various monitored and
measured workloads on AS/400e servers. The results can be used to compare relative
performance characteristics of processor features offered for AS/400e servers.
• Simple Mail Users (SMU): This relative performance measurement is derived by
performing high-volume Lotus Domino mail workloads on Dedicated Domino
processors. SMUs are representative of mail applications, particularly those that do
not perform any database related tasks. SMUs represent the estimated number of
concurrent light mail users for the Dedicated Domino processors. Reported values
reflect 70% processor utilization.
• Mail and Calendaring Users (MCU): This relative performance measurement is
derived by performing mail and calendaring functions. This workload is considerably
more complex than Simple Mail Users. The MCU workload represents users on a
Notes client who are reading, updating, or deleting documents in an e-mail database,
as well as lookups in the Domino directory and scheduling appointments and
invitations. Reported values reflect 70% processor utilization.
• Commercial Processing Workloads (CPW): CPWs are representative of commercial
applications, particularly those that do significant database processing in conjunction
with journaling and commitment control. The reported values for CPW represent the
capacity of a non-Domino workload available to support a Domino environment. The
reported CPW may be utilized by System Resource activities and Domino resource
extensions such as database accesses and external program calls. The amount of
CPW consumed reduces the available capacity to perform Domino workloads reflected
as SMU or MCU.
– Processor CPW is an approximate value reflecting the maximum amount of
non-Domino workload (10 to 15% of CPU) that can be supported.
– Interactive CPW is an approximate value reflecting the portion of Processor CPW that
can be used for application workloads performing interactive-based tasks.
