#Requires -Version 3 function Start-SpeedTest { <# .SYNOPSIS Report your internet Download and Upload speed. .DESCRIPTION Get-Speed leverages speedtest.net hosting servers. Get-Speed will identify the closest hosting server to you and perform a test download and upload. It will then report the average Download and Upload in Mbps. Get-Speed does not accept any parameters at this stage. .EXAMPLE Get-Speed .INPUTS None .NOTES Author: Mark Ukotic Website: http://blog.ukotic.net Twitter: @originaluko GitHub: .LINKS #> [CmdletBinding()] Param( ) Write-Output 'Retrieving configuration...' $uri = 'http://beta.speedtest.net/speedtest-config.php' [xml]$config = Invoke-WebRequest -Uri $uri -UseBasicParsing $ip = $config.settings.client.ip $isp = $config.settings.client.isp Write-Output "Testing from $isp ($ip)" $orilat = $config.settings.client.lat $orilon = $config.settings.client.lon Write-Output 'Retrieving server list...' $uri = 'http://www.speedtest.net/speedtest-servers.php' [xml]$hosts = Invoke-WebRequest -Uri $uri -UseBasicParsing Write-Output 'Selecting closest server...' $servers = $hosts.settings.servers.server # Work out the distance of each server $serverinformation = foreach($server in $servers) { $radius = 6371 [float]$dlat = ([float]$orilat - [float]$server.lat) * 3.14 / 180 [float]$dlon = ([float]$orilon - [float]$server.lon) * 3.14 / 180 [float]$a = [math]::Sin([float]$dlat/2) * [math]::Sin([float]$dlat/2) + [math]::Cos([float]$orilat * 3.14 / 180 ) * [math]::Cos([float]$server.lat * 3.14 / 180 ) * [math]::Sin([float]$dlon/2) * [math]::Sin([float]$dlon/2) [float]$c = 2 * [math]::Atan2([math]::Sqrt([float]$a ), [math]::Sqrt(1 - [float]$a)) [float]$d = [float]$radius * [float]$c New-Object PSObject -Property @{ Distance = $d Country = $server.country Sponsor = $server.sponsor Url = $server.url } } # Sort the distance of each server $closestserver = $serverinformation | Sort-Object -Property distance $location = $closestserver[0].sponsor $distance = $closestserver[0].distance Write-Output "Hosted by $location [$distance km]" # Perform the Download Test function Get-DataWCAsync{ param( [Parameter(Mandatory=$true)] $Url, [switch]$IncludeStats ) $wc = New-Object Net.WebClient $wc.UseDefaultCredentials = $true $start = Get-Date $global:downchange = Register-ObjectEvent -InputObject $wc -EventName DownloadProgressChanged -MessageData @{start=$start;includeStats=$includestats} -SourceIdentifier WebClient.DownloadProgressChanged -Action { filter Get-FileSize { "{0:N2} {1}" -f $( if ($_ -lt 1kb) { $_, 'Bytes' } elseif ($_ -lt 1mb) { ($_/1kb), 'KB' } elseif ($_ -lt 1gb) { ($_/1mb), 'MB' } elseif ($_ -lt 1tb) { ($_/1gb), 'GB' } elseif ($_ -lt 1pb) { ($_/1tb), 'TB' } else { ($_/1pb), 'PB' } ) } $time = ((Get-Date) - $event.MessageData.start) $averagespeed = ($eventargs.BytesReceived * 8 / 1MB) / $time.TotalSeconds $elapsed = $Time.ToString('hh\:mm\:ss') $remainingseconds = ($eventargs.TotalBytesToReceive - $eventargs.BytesReceived) * 8 / 1MB / $averagespeed $receivedsize = $eventargs.BytesReceived | Get-FileSize $totalSize = $eventargs.TotalBytesToReceive | Get-FileSize Write-Progress -Activity (" $url {0:N2} Mbps" -f $averagespeed) -Status ("{0} of {1} ({2}% in {3})" -f $receivedSize,$totalsize,$eventargs.ProgressPercentage,$elapsed) -SecondsRemaining $remainingseconds -PercentComplete $eventargs.ProgressPercentage if ($eventargs.ProgressPercentage -eq 100){ Write-Progress -Activity (" $url {0:N2} Mbps" -f $averagespeed) -Status 'Done' -Completed if ($event.MessageData.includeStats.IsPresent){ $global:down = [Math]::Round($averageSpeed, 2) } } } $null = Register-ObjectEvent -InputObject $wc -EventName DownloadDataCompleted -SourceIdentifier WebClient.DownloadDataCompleted -Action { Unregister-Event -SourceIdentifier WebClient.DownloadProgressChanged Unregister-Event -SourceIdentifier WebClient.DownloadDataCompleted } try { $wc.DownloadDataAsync($url) } catch [System.Net.WebException] { Write-Warning "Download of $url failed" } finally { $wc.Dispose() } } $serverurlspilt = ($closestserver[0]).url -split 'upload' $url = $serverurlspilt[0] + 'random2000x2000.jpg' Write-Output 'Testing download speed...'
