Hello, It seems that you did not use the option transport.socket.nodelay on # undocumented option for speed # http://gluster.org/pipermail/gluster-users/2009-September/003158.html as listed at [0]. This option has impact for small files. I did not test these suggested configs for v 3.x yet. Regards. Andre Felipe [0] http://www.techforce.com.br/news/linux_blog/glusterfs_tuning_small_files
