Red Hat Directory Server 7.1 for HP-UX11i v2 Integrity System Performance Tuning and Sizing Guideline

Red Hat Directory Server 7.1 Performance Tuning and Sizing Guidelines

13. 7-bit check plug-in: on (default)

14. Schema checking: on (default) leave it on because it specifies whether the database schema will be

enforced during entry insertion or modification. When measuring performance data based on exact

searches, this core server configuration attribute won’t affect the performance. So leave it alone as the

default value.

Selected Benchmark

DirectoryMark is selected as a benchmark for measuring performance of Red Hat Directory Server version 7.1. All

the test data in this document is collected base on the DirectoryMark version 1.0. The latest version is 1.3 at the

time of this writing, but it is only available on Windows 2000, 2003 servers, and Sun Solaris.

Test Machines

All the performance data are collected on the following machines:

Client:

Machine Class Machine Specification

SD32A Within partition, 4-way 1.6GHz ia64 8GB mem OS B.11.23 64-bit, 2 disks 89 GB

Server:

Machine Class Machine Specification

SD64B Within the partition one cell with 4 dual-core Intel Itanium2 9000 processors

counted as 8 1.6GHz CPUs, 64GB memory, OS B.11.23 64-bit, 2 disks 91GB

List 1: Client and Sever machine specifications.

Private LAN Configuration

All the test machines used for performance data collection are directly connected with Ethernet cables running point

to point between cards. All the tests are done assuming there are no heavy network traffics on the private LAN.

The configuration is as following:

Performance Monitoring Tools

vsar(Visual System Activity Reporter)

Vsar is an unsupported performance tool that periodically samples performance information from the kernel and

displays that information on a user’s terminal. For more information about vsar, please refer to:
