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.)
