Still trying to work through creating synthetic data for an out-of-the-box SharePoint performance test.  To create the data, create a new site collection (so it doesn’t interfere with anything else and is easy to clean up), and uploads all the test data.  The biggest downside right now is that the data is created and then uploaded, which requires enough disk space to make the data.  Not a huge issue for me, but possibly for you.

General idea came from a few places for the upload, and locally for the file creation.

#USER Defined Variables
#Specify the extension type of files you want uploaded
$strDocTypes = @(".docx",".xlsx", ".pptx", ".pdf")
#The max amount of data generated in MB
$maxSize = 50
#The max size one file could be in MB
$maxFileSize = 10
#Intermediate folder where the test data is placed
$fileSource = "F:TestData"
#New Content Database (for easy removal)
$dbName = "Portal_ContentDB2"
#New Site collection template
$template = "SPSPORTAL#0"
#Account owner
$siteOwner = "TESTAdministrator"
#Web Application address
$webApp = "https://portal"
#Site Collection Address
$siteCollection = "/sites/1"
# DO not edit anything beyond this line

#Create all the test data using FSUTIL

$rand = New-Object system.random
do {
	$guid = [guid]::NewGuid()
	$guid =  $guid.ToString()
	$fileName = $guid+$strDocTypes[$rand.next(0,$strDocTypes.length)]
	$rand1 = $rand.nextdouble()
	$rand2 = $rand.nextdouble()
	$rand3 = $rand.nextdouble()
	[int]$fileSize = 1048576*$rand1*$rand2*$rand3*$maxFileSize
	FSUTIL FILE CREATENEW $fileName $fileSize
	$fileTotalBytes = $fileTotalBytes + $fileSize
	$fileTotal = $fileTotalBytes/1024/1024
}
#Data generation keeps going until the amount of data is > $maxSize
while ($fileTotal -le $maxSize)

#Creation of the new content database and site collection
$siteCollectionURL = $webApp + $siteCollection
New-SPContentDatabase $dbName -WebApplication $webApp
New-SPSite -url $siteCollectionURL -OwnerAlias $siteOwner -Name "Test Doc Library" -Template $template -ContentDatabase $dbName

#uploading of all the generated data into the $siteCollectionURL/Documents folder
$spWeb = Get-SPWeb -Identity $siteCollectionURL
$listTemplate = [Microsoft.SharePoint.SPListTemplateType]::DocumentLibrary
$spFolder = $spWeb.GetFolder("Documents")
$spFileCollection = $spFolder.Files
Get-ChildItem $fileSource | ForEach {
	$spFileCollection.Add("Documents/$($_.Name)",$_.OpenRead(),$true)
}

Was looking for ways to generate synthetic test data for a SharePoint out-of-the-box install today, and ran into the SharePoint 2010 Load Testing Kit.  While it doesn’t help me in this stage of the project, I could see it being useful later or on other projects.

There appears to be a lot of dependencies though:

• Migration from 2007 to 2010
• As it collects info from your log files, you’ll need to have everything migrated for the scripts to work
• Data
• Apps
• Site Collections
• Etc.

Could be hot though!
