<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hello,<br>
<br>
It seems the performance issue with the switft ceilometer middleware is not new, it was raised before:<br>
<a href="https://bugs.launchpad.net/ceilometer/+bug/1337761" target="_blank">https://bugs.launchpad.net/ceilometer/+bug/1337761</a><br>
Which was abandoned with the Reason: The swift middleware is the site of much need for change, and this change in particular is pretty minor compared to those other needs.<br>
<br>
And discussions regarding the fate of the swift middleware. It is quite long:<br>
<a href="http://lists.openstack.org/pipermail/openstack-dev/2014-July/041522.html" target="_blank">http://lists.openstack.org/pipermail/openstack-dev/2014-July/041522.html</a><br>
<br>
It seems that the swift middleware will have to change quite a bit in the future to address the performance issue, and it could take a while and won't make it in Icehouse 2014.1.3.<br>
<br>
I think Eoghan Glynn should be consulted on this matter as well, since he is a ceilometer core and he participated in the discussions and should be able to tell if this commit should be accepted as a FFE.<br>
<br>
Still, IMO, a 10-20% performance drop is still better than not working.<br>
<br>
I say it's worthy.<br>

</span>I don't have juno env to measure the performance now but I think it should be observed in<br>
juno from the code point of view.<br>

</span>I think so too.<br>
<br>
Thanks again!<br>
