Measuring Website Response (and Execution Times)

PowerShell 3.0 and later

Sometimes it is important to know just how long a command takes. For example, to monitor web site response times, you could use Invoke-WebRequest. Measure-Command measures execution time.

$url = 'http://www.powershell.com'


# track execution time:
$timeTaken = Measure-Command -Expression {
  $site = Invoke-WebRequest -Uri $url
}

$milliseconds = $timeTaken.TotalMilliseconds

$milliseconds = [Math]::Round($milliseconds, 1)

"This took $milliseconds ms to execute"

Getting Milliseconds from a TimeSpan and Rounding the Result

It returns a TimeSpan object which in turn contains a property “TotalMilliseconds”. Use Round() provided by the “Math” type to round the result. In this example, the milliseconds are rounded to the first digit after the decimal.
