[Gluster-users] Very poor performance - 2 Peers, 500KB = 14 Seconds

i looked at iotop.

One file will be written (Average Speed 250k/s). After the file is written nothing happens for 1 or 2 seconds. Then the next procedure for writing will be started.
The cpu is idle and very bored.

Does any one has any clue for me?

Hopeful greetings,
