Even a 40GB file was faster on xfs. I'm running 4 servers - glusterfs on xfs - in production. But that said, I have experienced instant server kill on some occations whitch may be from accessing corrupted files (from a xfs disk) and trying to write them in glusterfs. Reading yours (Kevan) thoughts here will make me take a new look at this possible file system problem.
