> *Problem*
> We have a feature called "default path modes". When IGFS is started, it creates several special folder for each mode (PRIMARY, DUAL_SYNC, DUAL_ASYNC, PROXY).
> Our idea was that it would be convenient for users. However, in reality users are almost never need any of these directories, but:
> 1) It degrades Hadoop file system performance, as a path with "PROXY" mode forces secondary file system creation on the client.
> 2) It degrades path mode resolution performance on the server because we always has at least 4 modes to compare against.
> *Solution*
> Switch default flag for this property to false.
