Obviously you fail to understand my point: the design of glusterfs implies
that it can be as fast as a non-distributed fs. If you have not understood
this by now you should stay another 10 years on this list.
As glusterfs should only read from a single node, and write concurrently to
all nodes it must only be slower than a non-distributed fs if your network is
not designed according to the needed paths. Glusterfs being
slow is not by design but by implementation.

Uh, really no comment.

Probably you are not talking about linux based NFS experience. The last time
we used userspace nfs (very long ago) on linux it was slow _and_ amazingly
buggy. Many thanks to Neil that he made kernel nfs what it is today.

Well, people were _paid_ for years now and came up with this mess. And you
want me to implement it for free in what time? If you give me the bucks that
were paid during the last decade you can be sure the solution is a lot
better, easier to configure, and thought-through.

Yes, we perfectly agree on that.
