guidelines about what performance gains you may expect through its use.
In some exceptional cases, some applications are better served by disabling
simultaneous multithreading.

iSeries for Domino performance terminology

iSeries for Domino models are specially priced and configured for Domino
workloads. iSeries for Domino separates mail, instant messaging, and
collaborative applications while automatically balancing and adjusting
performance. With iSeries for Domino servers, you can run non-Domino
workloads without restriction, even when the Domino server is not active.
Note: This is unlike the Dedicated Server for Domino servers (now
from marketing
The iSeries for Domino servers do not have processing guidelines for
non-Domino workloads. Performance is not measured using the CPW
measurement, but a Mail and Calendar User (MCU) measurement.
Mail and Calendar Users
Mail and Calendar Users (MCU) is a relative performance measurement derived
by performing mail and calendar functions using Domino and Notes clients. The
MCU workload is significantly more complex than the Simple Mail Users (SMU)
measured workload.
The MCU workload represents concurrent users on a Notes client who are
reading, updating, or deleting documents in an e-mail database. It also
represents users who are performing lookups in the Domino Directory, and
scheduling calendar appointments and invitations. Reported values reflect 70%
processor utilization to allow for growth and peak loads in excess of customer
workload estimates.
See "Summary of today's iSeries" on page 81 for a listing of the MCU rating for
each iSeries for Domino server.
