What are the main advantages of setting up eZ DFS in a cluster environment, instead of just using a centralized var dir (mounted NFS)?

I can see that the performance of each server could be a bit better, since it will create local copies on each server, instead of always serving it directly from the NFS mount. But varnish should solve that "problem".

Anyone have experience with it?

Varnish does not solve cache files shareing between ez publish installs.

But you are correct that serving static files (images / js / css / files) would be much faster by using Varnish and direct urls to nfs mount, not sure if this is possible with dfs though.
