+<h1 id="PerformanceTweak">Performance tweak for busy Cluster</h1>
+<p>Starting from v3.2.0, Apache Traffic Server can handle multiple internal cluster connections, 
+and we can tweak for the Cluster threads and connections:</p>
+<ul>
+<li>
+<p>Increasing Cluster threads:
+ In the cluster env, the current performance of the Cluster threads will consume the same cpu
+ usage as net threads, so you may adapt the ET_NET &amp; ET_CLUSTER at about 1:1. For example, on
+ a 24 cores system, set ET_NET threads to 10, ET_CLUSTER threads to 10. 
+        traffic_line -s proxy.config.cluster.threads -v 10</p>
+</li>
+<li>
+<p>Setup the Cluster connections:
+ In the Cluster, the internal connections is TCP and limited by ET_CLUSTER threads and network
+ performance, we can increase the connections to archive better performance.
+    traffic_line -s proxy.config.cluster.num_of_cluster_connections -v 10</p>
+</li>
+</ul>
+<p>with these tweak, we can archive about 10gbps traffic for the internal cluster transfer speed.</p>
