Armando,<br>
<br>
<br>
Thanks for sharing your experience. It's interesting to hear
that you run 5.5.<br>
<br>
My problem is Swift performance (only Swift, I wasn't interested
in Nova). I couldn't get beyond 6-7 writes/sec with 5 node Swift
cluster running on CentOS 5.7 (2.6.18-238.19.1.el5) and with
RF=3. After troubleshooting for a couple of weeks, we came to
conclusion that CentOS 5.x is not supported. See my explanation
here: <a class="moz-txt-link-freetext" href="https://lists.launchpad.net/openstack/msg06303.html">https://lists.launchpad.net/openstack/msg06303.html</a><br>
<br>
Right now decision was made to upgrade to CentOS 6.x, but it
will take a while.<br>
<br>
Did you run any performance tests at all? Would be interesting
to see some swift-bench figures if available.<br>
<br>
<br>
Many thanks,<br>
Rustam.<br>
