[Gluster-users] Gluster scalability ?

we have a small gluster setup currently running on two nodes, with 2x2TB
disks each, serving a distributed-replica volume.
We are planning to deploy this setup over more nodes, 10 to start with,
possibly 20 to 50 in the future.
We are already noticing a significant amount of IO operations across the
two nodes when writting data to the filesystem, thus we were wondering:
Will the computational overhead induce by Gluster remain more or less
constant when adding more nodes, or is this overhead increasing with the
number of nodes that form a volume ?
I understand that under specific conditions, a client will query all
nodes in order to find the actual location of a specific file: this
sounds like it could become a problem if the number of nodes becomes large.
Thanks for your insights,
