<p>Dear Mark,</p>
<p>we have also a gluster 3 node setup with a replica-3-volume which
is exported via cifs, and two dispersed volumes which</p>
<p>are exported via cifs and fuse. As already known, the small file
performance could be better. Larger file performance is ok.</p>
<p>We have similar volume options reconfigured. <br>
</p>
<p><br>
</p>
<p>Could you provide more information, e.g. workload and file size
and your disk setup would be nice to know. <br>
</p>
<p><br>
</p>
<p>Regards,</p>
<p>Felix<br>
