that sounds good, Option to configure relative priorities of READ and<br>
WRITE operations would be probably sufficient in my case (as long as<br>
it really affects the operations throughput).<br>
<br>
But what if you wanted to differentiate write/read priorities from<br>
different clients? maybe it's worth thinking about some way to enable<br>
this?<br>

<br>
Oh, these options will be on server side. So all clients will see same<br>
priorities. That is probably the reason why the Original developer<br>
didn't allow these priorities to be changed. I am not sure how we can<br>
configure in a generic way. Any thoughts?<br>

All clients observing the same set of priorities does address the initial problem discussed here.<br>
<br>
Addressing the second one - configurable priorities based on client's identity is something that we intend addressing as part of quality of service in Gluster.next releases.<br>
<br>
Mateusz - are there other use cases related to traffic shaping/throttling that would interest you?<br>
<br>
Thanks,<br>
