powershell run script in parallel

Question

i'm using windows server 2003, now i have a script to restart one specific service, can someone guide me how to run this script in parallel? i already use start-job, but seems it only run in backround but still sequential, below is my script:

file name: restart-service.ps1

$start = Get-Date
$Serverlist = Get-Content -path C:\Computers.txt

ForEach ($Server in $Serverlist){
start-job -scriptblock {param($Server) Restart-Service -InputObject $(Get-Service -ComputerName $Server -Name "aspnet_state")} -ArgumentList $Server
}
Get-Job | Wait-Job
Get-Job | Receive-Job
$end = Get-Date
$timespan = $end - $start
$seconds = $timespan.TotalSeconds
Write-Host "This took me $seconds seconds."

or this

$start = Get-Date
$Server = Get-Content -path C:\Computers.txt

$scriptblock = {
    Param($Server)
    Restart-Service -InputObject $(Get-Service -ComputerName $Server -Name "aspnet_state")
}
$Server | % {Start-Job -Scriptblock $scriptblock -ArgumentList $_ | Out-Null}
Get-Job | Wait-Job | Receive-Job

$end = Get-Date
$timespan = $end - $start
$seconds = $timespan.TotalSeconds
Write-Host "This took me $seconds seconds."

but i only can see the result, but can not see any result related information of my server's IP, can someone help me how to improve it...

This is the Direction, tweak it for your specific needs... add timer etc...

$Serverlist = Get-Content -path C:\Computers.txt

Foreach ($Server in $Serverlist)
{
    Start-Job -Name "$Server-Job" -ScriptBlock {
    Get-Service -ComputerName $args[0] -Name "aspnet_state" | Restart-Service 
    } -ArgumentList $Server
}

It will Create a job with the ServerName for each server, to Get the Job status/info, use:

Get-Job | Receive-Job
