AppFabric: Is there a difference between standard and named cache?

Is there a difference between the default cache and naming in AppFabric? It looks like the msdn documentation:

http://msdn.microsoft.com/en-us/library/ee790985%28v=azure.10%29.aspx

doesn't seem to apply to any differences.

The reason I ask is because in our deployment environment we need to use the same application cache host due to the lack of servers. Thus, for any client who wants to use the default cache, I plan to replace this cache name with "dev-default" with the name cache or "test-default" with the name cache. I am wondering if there is a difference between the default cache and the named cache in terms of storage, performance, etc. Is this "name cache redirection" some kind of impact on appFabric inside?

We are using the xml-based configuration for appfabric and from what I see in ClusterConfig.xml there seems to be no difference between the default cache and the naming if you create the cache with:

Command Remove-Cache -CacheName MyNamedCache

 <cache consistency="StrongConsistency" name="default" minSecondaries="0">
    <policy>
      <eviction type="Lru" />
      <expiration defaultTTL="10" isExpirable="true" />
    </policy>
  </cache>
  <cache consistency="StrongConsistency" name="MyNamedCache" minSecondaries="0">
    <policy>
      <eviction type="Lru" />
      <expiration defaultTTL="10" isExpirable="true" />
    </policy>
  </cache>
