Get-CINetworkAdapter, extremely slow in bulk (20 minutes)

Hi,

I'm trying to get all Vm's and thier external ip address, to do some scripted DNS.

But it takes almost 20 minutes to complete for 136 machines.

@ PowerCLI 5.1 Release 2 build 1012425 & Powershell 2.0

 

$vAppNetworkAdapters = @()

$vAppsVms = @()

$vApps = @()

$myOrg = $null

$vCloud = $null

$vCloud = Connect-CIServer -Server "host.contoso.com" -Credential (Get-Credential -Credential "User")

if($vCloud -ne $null)

{

Write-Host "Is connected: $($vCloud.IsConnected)"

}

$myOrg = Get-Org -Name "Development"

$vApps = Get-CIVApp -Org $myOrg            #Count:   8

$vAppsVms = Get-CIVM -VApp $vApps          #Count: 136

Measure-Command {$vAppsVms | %{

##get-externalnetwork

$adapter = Get-CINetworkAdapter -VM $_ -Primary $true

Write-host ("Vm: " + $_.Name + ", external ip: " + $adapter.ExternalIPAddress)

}}

20 minutes is not so bad you say? Well, we intend to get around a thousand machines running in this enviroment, looking at a 3 hour execution time.

I've tried to extract all the network adapters first, and then doing selects, but it takes almost exactly the same amount of time.

Measure-Command {$adapters = Get-CINetworkAdapter -vm $vAppsVms -Server $vCloud}

Anyone got any pointers? I really wan't to find out if there's a slowdown somewhere on our servers, or if it is just the implementation of the "Get-CINetworkAdapter" command, and if there is a way around it.

Best Regards

Daniel
