SharePoint Developer Dashboard

From SharePoint 2010 Management Shell on the WFE:

 $webSvc =[Microsoft.SharePoint.Administration.SPWebService]::ContentService

$webSvc.CollectSPRequestAllocationCallStacks = ‘True’

$webSvc.Update()

$webSvc.DeveloperDashboardSettings.EnableDiagnosticMode()

After this runs, you will see a green icon at the top right corner of the page. Click the green icon to view query statistics, server information, user information, etc.
