Can anyone help me troubleshoot why this PSCX cmdlet 'Write-Zip' is so slow? It takes 1.5 hours when the DotNetZip library can ZIP the same folders in about 20 minutes. (The issue with the DotNetZip library is that it chokes with large files, so I switched over to PSCX which is perfect, cool little progress bar and it actually works too, just very slowly).
Here is some sample code, let me know if you need to see anything else.
$ElapsedTime = [System.Diagnostics.Stopwatch]::StartNew()
Write-Host "Script Started at $(get-date)"
Import-Module Pscx
Import-Module BitsTransfer
Write-Host "Just imported the BitsTransfer and Pscx modules"
Write-Host "*** Starting backup portion of script ***"
foreach($i in $appServers) {
if (!(Test-Path -path \\$i\c$\newDeploy)) {
New-Item \\$i\c$\newDeploy -type directory
Write-Host "Just created newDeploy folder on $i"
}
if (!(Test-Path -path \\$i\c$\newDeploy\backup)) {
New-Item \\$i\c$\newDeploy\backup -type directory
Write-Host "Just created newDeploy\backup folder on $i"
}
if(!(Test-Path \\$i\c$\newDeploy\zipper.ps1)) {
Start-BitsTransfer -Source \\$appDeployServer\c$\newDeploy\zipper.ps1 -Destination \\$i\c$\newDeploy
Write-host "Just added zipper.ps1 to $i"
}
}
foreach($i in $appServers) {
$sessionForI = New-PSSession -computername $i
Invoke-Command -Session $sessionForI -ArgumentList $aosFolder, $i, $ElapsedTime -ScriptBlock {
