Delay opening documents on some workstations
I’ve recently noticed a delay of almost 5 seconds when opening documents from SharePoint on some workstations. After a bit of investigation I discovered that this was caused by Internet Explorer Automatic Configuration. On the workstations that were experiencing a delay the “Automatically detect settings” option was enabled. After disabling this option documents opened straight away.
To locate these settings in Internet Explorer go to Tools –> Internet Options –> Connections tab–> LAN Settings
