Name caches in Distributed File Systems provide the following advantages:
*Reducing of network traffic to a great extent because the local cache is capable of handling a reasonably large number of accesses present remotely
*Lessening of load on the server thereby causing reduction of server congestion

In computing a cache is a hardware or a software component that stores Data for future requests so that the data can be served faster.
This data can be as a result of earlier computations or a copy of data stored somewhere else.
Name catches are very important in file systems.
WHY WE CACHING:
1) Most of the recently accessed disk blocks are retained.
2) Repeated accesses to a block in a cache can be handled without the involvement of the disk.
ADVANTAGES
A) It reduces delays thus reducing network traffic
B) It reduces contention for the disk arm.
With this it is always easy to access data of names stored in different locations which have taken time without access.
