ECG007.0897 WHITE PAPER (cont.) 7... 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

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
