No session support needed

By default, session affinity is enabled in WebSphere. If none of your applications needs session support, you can remove the CloneID in the plugin-cfg.xml file to make your request processing faster. Doing so eliminates the time-consuming comparison process:

   <ServerCluster Name="HACluster">

        <Server CloneID="u307p2vq" LoadBalanceWeight="2" 
Name="HAClusterServer1"></Server>

        <Server CloneID="u307p48r" LoadBalanceWeight="3" 
Name="HAClusterServer2"></Server>

        <Server CloneID="u307p62u" LoadBalanceWeight="4" 
Name="HAClusterServer3"></Server>

        <Server CloneID="u307p71m" LoadBalanceWeight="5" 
Name="HAClusterServer4"></Server>

    </ServerCluster>

However, if any application in your appservers is stateful, you will lose all state information during a failover. Remember that this setting is for the whole server cluster, not for a single Web application. It is not necessary to disable the server session support for session-less clients.
