Filip,
Sorry for the confusion. I am testing this on my local machine at the moment.
I am assuming in an environment with multiple machines I'd have the actual IP
address of the machine here correct?
How about my settings for following:
- channelSendOptions
this is good, set to 8 means asynchronous. this is for best performance,
and assuming you have sticky sessions
- NioReceiver maxThreads
good value,
- McastService frequency and dropTime
most folks increase drop time to 10 seconds or so, as when networks get
busy, 3seconds sometimes cause false positives
Anything terribly wrong for a production environment?
no, it's all good!
Thanks,
Jim

address="127..."
this means you have two tomcat instances on the same machine?
is this what you want?

I am new to Tomcat 6 (upgrading from Tomcat 4) and I would love to benefit from
the features of clustering. However, I am concerned about performance. Are
people successfully using the clustering features of Tomcat 6 in production?
If so, are your settings a lot different than mine:
<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster" channelSendOptions="8" > <Manager className="org.apache.catalina.ha.session.DeltaManager" expireSessionsOnShutdown="false" notifyListenersOnReplication="true"/> <Channel className="org.apache.catalina.tribes.group.GroupChannel"> <Membership className="org.apache.catalina.tribes.membership.McastService" address="228.0.0.4" port="45564" frequency="500" dropTime="3000"/> <Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver" address="127.0.0.1" port="4010" autoBind="100" selectorTimeout="5000" maxThreads="6"/> <Sender className="org.apache.catalina.tribes.transport.ReplicationTransmitter"> <Transport className="org.apache.catalina.tribes.transport.nio.PooledParallelSender"/> </Sender> <Interceptor className="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector"/> <Interceptor className="org.apache.catalina.tribes.group.interceptors.MessageDispatch15Interceptor"/> </Channel> <Valve className="org.apache.catalina.ha.tcp.ReplicationValve" filter=""/> <Valve className="org.apache.catalina.ha.session.JvmRouteBinderValve"/> <ClusterListener className="org.apache.catalina.ha.session.JvmRouteSessionIDBinderListener"/> <ClusterListener className="org.apache.catalina.ha.session.ClusterSessionListener"/> </Cluster>
I'd love to hear any performance tips people have.
Thanks,Jim
