Intel 7xx Servers, 170 Servers, AS/400 RISC Server manual Relative Performance Metrics

yCGI: HTTP invokes a CGI program which builds a simple HTML page and serves it via the HTTP server. This CGI program can run in either a new or a named activation group. The CGI programs were compiled using a "named" activation group unless specified otherwise.

Web Server Capacity Planning: Please use the IBM Systems Workload Estimator to do capacity

planning for Web environments using the following workloads: Web Serving, WebSphere, WebFacing, WebSphere Portal Server, WebSphere Commerce. This tool allows you to suggest a transaction rate and to further characterize your workload. You’ll find the tool along with good help text at: http://www.ibm.com/systems/support/tools/estimator . Work with your marketing representative to utilize this tool (also chapter 23).

The following tables provide a summary of the measured performance data for both static and dynamic Web server transactions. These charts should be used in conjunction with the rest of the information in this section for correct interpretation. Results listed here do not represent any particular customer environment. Actual performance may vary significantly from what is provided here.

Relative Performance Metrics:

y“Relative Capacity Metric: This metric is used throughout this section to demonstrate the relative capacity performance between primitive tests. Because of the diversity of each environment the ability to scale these results could be challenging, but they are provided to give you an insight into the relation between the performance of each primitive HTTP Server test..
