I noticed today and yesterday that running my site on local host is very slow. I highly doubt this is a code issue as when I put it up on my live site it went fast.
My site load time in debug mode went down from 3 minutes to 35 seconds when I set the Debug for "x86" in place of "Any CPU" in Visual Studio 2015. This is done by simply choosing "x86" from the DropDown in the visual studio toolbar.
