Happened with me using SharePoint 2013 - calling the SP 2013 restful service to search the index, results come back quickly except for some calls it takes long time. This slowness occured almost every 10 minutes.

A simple, yet cool, feature in Visual Studio 2010 is that you can connect Server Explorer to your SharePoint site and view its content hierarchy … this is helpful in giving you a quick view of your site content without the need to switch your IDE window… for some item types like document libraries and lists, it gives you quick access to an SP item through a link to the SharePoint page to manage it
P.S: I tried this with VS 2010 and SharePoint 2010
