Bonnie++ command:  ./bonnie++ -u 99:99 -d /var/boot -s 2000

The system I'm testing on has 1GB RAM.  /var/boot is the glusterfs
mount via fuse.

The transport is tcp but all on localhost.  Here's the glusterfsd.vol:

volume posix1
  type storage/posix
  option directory /mnt/gluster/gfs2

volume locks1
    type features/locks
    subvolumes posix1

volume brick1
    type performance/io-threads
    option thread-count 8
    subvolumes locks1

volume server-tcp
    type protocol/server
    option transport-type tcp
    option auth.addr.brick1.allow
    option transport.socket.listen-port 6996
    option transport.socket.nodelay on
    subvolumes brick1

Here's the client config:

volume localhost-1
    type protocol/client
    option transport-type tcp
    option remote-host localhost
    option transport.socket.nodelay on
    option transport.remote-port 6996
    option remote-subvolume brick1

volume writebehind
    type performance/write-behind
    option cache-size 4MB
    subvolumes localhost-1

volume readahead
    type performance/read-ahead
    option page-count 4
    subvolumes writebehind

volume iocache
    type performance/io-cache
    option page-size 1MB
    option cache-size 1GB
    option cache-timeout 1
    subvolumes readahead

volume quickread
    type performance/quick-read
    option cache-timeout 1
    option max-file-size 64kB
    subvolumes iocache

volume statprefetch
    type performance/stat-prefetch
    subvolumes quickread
