> I have a few Glusterfs clusters. They are all running version 3.0.5.
> Both servers and clients are on Ubuntu 64 bit systems.
> My clusters are configured as Distributed and Replicated over Gigabit
> network. About 5 clients are reading and writing millions of files in
> all sizes to my filesystem.
>
> The volumes are exported using the fuse-based Glusterfs client. Volume
> size is usually 115 TB.
>
> I am experiencing performance degradation as the number of folders and
> files on my gluster filesystem grows.  Running a simple command like
> ls can take minutes to complete.
>
> Cocurrent write performance is pretty poor.
>
> Is this performance degradation expected behavior?
>
> Are there any performance improvements related to concurrency and
> small files in Glusterfs 3.1?
>
> Any operating system or RAID configurations the community can
> recommend to help with performance? (We are mostly using Adaptec 5805
> RAID controllers on or storage nodes.)
