About Performance and Scalability

Every implementation of Siebel Business Applications is unique. Your Siebel application architecture, infrastructure, and configurations might differ depending on your business model.

Performance and scalability are defined as follows in the context of this guide:

• Performance. A Siebel application's ability to function, generally measured in response time or throughput.

  For example, measures of performance might include the time required to log in to the Siebel application or to display a Siebel view in the Siebel Web Client, or the volume of transactions (sometimes referred to as requests) that a server component can process in a given time period.

  Some typical inhibitors of performance are inadequate hardware, excessive network round trips, heavy customizations, and poor networking infrastructure.

• Scalability. A Siebel application's ability to continue to perform well as volumes increase.

  Scalability is generally measured in hardware terms; for example, maintaining acceptable performance after adding new processors on existing computers (vertical scalability) or new Siebel Server computers (horizontal scalability) to process an increased number of users. Some typical inhibitors of scalability are an inflexible application module structure and an inability to run parallel processes.
