The estimated performance and number of users in customer environments varies.
• 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
amount of CPW consumed reduces the available capacity to perform Simple Mail Users
(SMU).
– 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 workloads performing interactive-based tasks (5250). AS/400e
Dedicated Server for Domino can be effectively managed when there is no Interactive
CPW (Interactive CPW = 0) available for application workloads. Multiple system
operators performing simultaneous interactive tasks is not supported.
• Any job started from a console (green screen) to perform system administration
function is not considered interactive work if it is the only interactive job running.
• Any system administration job submitted to batch is not considered interactive
work.
• Operations Navigator (GUI administration functions) is not considered interactive
work for the purposes of CPW calculations.
• 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. The
reported values reflect 70% processor utilization to allow for peak loads in excess of
customer workload estimates.
Achieving the estimated Simple Mail User measurement requires a fully configured
server, including additional memory and disk.
• 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.
