Measuring Website Response (and Execution Times)

by Mar 13, 2015

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 = ''

# 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"

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.
