Hi Armando,


Thanks for sharing your experience. It's interesting to hear that you 
run 5.5.

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: 
https://lists.launchpad.net/openstack/msg06303.html

Right now decision was made to upgrade to CentOS 6.x, but it will take a 
while.

Did you run any performance tests at all? Would be interesting to see 
some swift-bench figures if available.


Many thanks,
Rustam.
