<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Using swift stat probably isn't the best way to determine cluster<br>
performance, as those stats are updated async, and could be delayed<br>
quite a bit as you are heavily loading the cluster. It also might be<br>
worthwhile to use a tool like swift-bench to test your cluster to make<br>
sure it is properly setup before loading data into the system.<br>
