. . This section:
. .
. .
defines two perceptions of performance
. .
. .
describes performance analysis
. .
. .
discusses standard and customized benchmarks as a performance
. .
. .
measuring tool
. .
. .
describes the testing methodology used during the study while focusing on
. .
Novell NetBench as the benchmark tool used for measuring performance of
. .
. .
the CPU, memory, and disk subsystem.
. .
. .
Data gathered from Novell NetBench testing is presented and configuration recommendations are
. .
provided based upon data analysis and the experience of Novell and Compaq engineers.

Performance Characteristics

. .
. .
. .
Performance can be viewed in one of two ways. To a system administrator, performance means
. .
effective management of system resources. A system administrator's concerns are system
. .
. .
throughput and utilization. To an end user, however, performance is measured by system response
. .
time. In practice, it is necessary to balance the two perspectives; understanding that a change
. .
. .
made to improve response time may require more system resources.
. .
. .
The purpose of this section is to provide the customer with an understanding of how GroupWise
. .
Server performed under various test configuration scenarios or benchmarks. Based on results
. .
. .
from these tests, information is provided that can be used as a guideline for gauging the response
. .
time, throughput, and capacity expected of Novell GroupWise running on a Compaq server.
. .
. .

Performance Analysis

. .
. .
. .
Performance analysis is an ongoing, interactive process necessary for determining whether or not
. .
your server is performing as it should. Performance analysis that is required as a part of
. .
. .
performance management includes
. .
. .
Understanding your user requirements
. .
. .
Monitoring your server and network load patterns
. .
. .
. .
Making appropriate modifications to your configuration to achieve
. .
optimal use of resources
. .
. .
For the performance analysis investigation, Novell and Compaq engineers used a standard
. .
. .
benchmark tool to examine the following GroupWise Server system resource areas:
. .
. .
System Processor (CPU) Performance
. .
. .
. . Memory
. .
. .
Disk Subsystem
. .
. .
Bus Architecture (PCI versus EISA)
. .
. .
. .
File Systems
. .
. .
Networking
