AS/400e Dedicated Server for Domino
138 AS/400e System Handbook
Relative performance measurements (described in the following list) are derived by
performing various monitored and measured workloads on AS/400e servers. The results
(reported values) can be used to compare relative performance characteristics of processor
features offered for AS/400e servers.
Note: The estimated number of users and performance in customer environments varies.
Achieving estimated Simple Mail Users requires a fully configured server including additional
memory and disk.
• Simple Mail Users (SMU): This relative performance measurement is derived by
performing high-volume Lotus Domino mail workloads on Dedicated Domino
processors. Simple Mail Users are representative of mail applications, particularly
those that do not perform any database-related tasks. Simple Mail Users represent the
number of concurrent light mail users for the Dedicated Domino processors. These
reported values reflect 70% processor utilization to allow for peak loads in excess of
customer workload estimates.
• 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 Workload (CPW): This relative performance measurement
is derived by performing Commercial Processing Workloads on Dedicated Domino
processors. Commercial Processing Workloads are representative of commercial
applications, particularly those that do significant database processing in conjunction
with journaling and commitment control. The reported values for CPW do not
represent a guaranteed level of capacity to perform non-Domino workloads. The
reported CPW may be used by System Resource activities and Domino Resource
extensions (for example, database accesses, external program calls, and so on). The
