Recently we have had the need to upload large batches of documents to SharePoint to accessed externally. The issue comes when we use either the drag and drop or explorer functionality to copy documents and folders into SharePoint.
Now I read lots of articles on performance tuning and things you should and should not do. We have a relatively small single server SharePoint 2010 installation that is running on Windows 2008 with SQL 2008.
It should not be having any performance issues!
After doing some digging though I found a very simple solution.
Internet Explorer was the culprit in this case. Since the explorer view or the drag and drop is controlled primarily by IE, then it only makes sense that the settings in IE can affect the file transfer speeds.
- In Internet Explorer, on the Tools menu, click Internet Options.
- On the Connections tab, click LAN settings.
- On the Local Area Network (LAN) Settings dialog, under Automatic configuration, clear the Automatically detect settings check box.
