Benchpress

Benchpress is a quick and easy benchmarking toolkit for PowerShell

It helps you write and manage simple comparative benchmarks. You can use this information to make your scripts more efficient.

For instance, here’s a quick Benchmark to determine if you should use Foreach statement or foreach object

Measure-Benchmark -Technique @{
    ForeachObject = { 1..100 | Foreach-Object { $_ } }
    ForeachStatement = { foreach ($n in 1..100) { $n }}
}

You can install Benchpress from the PowerShell Gallery:

Install-Module Benchpress -Scope CurrentUser -Force

Benchmark comes with a number of PowerShell Performance experiments.
