High-performance pipelines

Performance is very important in automation scenarios. Often, scripts and cmdlets work with more than a few objects and connect to more than a few remote systems to collect data.

This recipe demonstrates the importance of filters when accessing the filesystem, as well as the Windows event log.

Getting ready

Install and start PowerShell Core. If you want to follow along with the Windows event log example, please use a virtual machine with a Windows version that is compatible with PowerShell...
