From: "Pedro Ruivo" <pedro(a)infinispan.org&gt; To: "ispn-dev" <infinispan-dev(a)lists.jboss.org&gt; Sent: Tuesday, June 4, 2013 10:12:49 AM Subject: [infinispan-dev] Infinispan 5.3 and the new JGroups bundler Hi all, In Infinispan 5.3 we are allowing message bundling due to "recent" improvements made in JGroups' bundler. The new bundler is the default in JGroups 3.3 but if you are using the old bundler (UDP.bundler_type="old"), please may consider to change it to use the new bundler (UDP.bundler_type="new"). If you don't want to change it, please consider that the old bundler can lead a performance degradation in a low throughput system (when you have 1 or 2 threads performance operations). Note that, in the old blunder, the messages are blocked until (default values, of course you can tunning this values to match to your application): * 30 milliseconds are expired; or * 64k bytes are ready to be sent. Recall that this warning is valid for Infinispan 5.3 (and superior in the future). Thank You.

Hey Pedro, >> 1) What is the default bundler used in JGroups 2.7.x? > > Bela is the right person to answer this, but I think the new bundler was > created only in JGroups 3.3.x. So what happens if the JGroups 2.7.x config file has UDP.bundler_type="new"? Will it just be ignored?

Will it just be ignored? bundler_type doesn't exist in 2.7, so this will throw an exception and the stack won't be started -- Bela Ban, JGroups lead (http://www.jgroups.org) _______________________________________________ infinispan-dev mailing list infinispan-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/infinispan-dev

I wouldn't be so sure: in 3.3, we now bundle OOB messages, so the tag to use to skip bundling is DONT_BUNDLE, but in Infinispan < 5.3, they used OOB to achieve this. This is not supported, so bundling of OOB messages might break things. Or it might as well work, but I for one won't make any guarantees...:-)
