     Fuse is fuse-2.7.0-1.  Can you give me an example of a volume
specification file please?

Chris,
posting your volume specification files will help us tune it futher. Also,
what fuse version (kernel module) are you using?

thanks,

      Hey all,

      Running glusterfs-1.3.5 on CentOS5 on the server 4.5 on the
server.  Ran iozone to see what the performance was.  Gluster was
about 1ms/read slower than NFS.  Doesn't sound like much I know but
when your reading through 800MB of medical image it adds up.

      Would someone please be so kind as to give some guidance of where to
look to tune this?  And can it even be tuned to as fast as NFS.
Faster is better.

      Thanks much.
