Planning Capacity and Sizing
Begin system sizing during the design phase, since volumetric considerations influence the system
design. For example, some high yield process transactions like the task list must be performed
frequently. The task list transaction can perform well in a test environment, but can result in
performance problems when many users simultaneously execute the transaction. Each transaction
queries the database that must return results in under one second. If the browser is unable to render
screens in a timely fashion, aggregate demand on the database adversely affects user performance.
If there are not enough resources to accommodate thousands of simultaneous users querying the
database, performance degrades.
