Case Study #1

Disk Usage Study SummaryComponents working well in isolation could impact performance when executed in parallelFighting over disk dramatically impacts performance

For all involvedDisk seeks can cut throughput by 90%

Schedule all work that can wait as Idle tasksSee Task Scheduler documentation on MSDN

Hardware Device not performingJohan ArwidmarkChief Technical ArchitectKnowledge Factory

Case Study #2

Hardware Device Case Study SummaryOne bad component can disrupt numerous good componentsHigh usage of any single resource can cause performance issuesSpending too much CPU at DPC impacts performance
