Internal NuGet Feed - folder vs IIS

Is there a benefit to hosting an internal (re开发者_Python百科mote) NuGet feed through an IIS website vs simply using a shared network folder?

If shared UNC access is available, then it is definitely the simpler solution to create an internal feed. However, if the feed has a large number of packages, then the performance will be better when using http because of the caching it's able to do. In the UNC case, NuGet needs to crack open the packages on every operation.
