Hi, Are you just using a single brick? Gluster is a scale-out NAS file system so is usually used when you want to want to aggregate the disk performance and disk space of many machines into a singe Global Name Space. ocfs (cluster filesystem) is more for when you have a single disk volume attached via SCSI to many machines. More than one machine cannot for instance access the same ext4 filesystem concurrently. ocfs provides a locking mechanism allowing many systems to access the same SCSI device at the same time. Gluster is to NFS as OCFS is to EXT4 (kinda). The lag your getting might be due to FUSE (Filesystem in Userspace). FUSE allows weird and wonderful filesystems to be mounted in userspace meaning kernel support is not required. This is typically much slower than kernel enabled filesystems.
