[ https://issues.jboss.org/browse/ISPN-4372?page=com.atlassian.jira.plugin.... ] Alan Field commented on ISPN-4372: ---------------------------------- I was comparing the performance in Infinispan 6 and 7 which has much different performance characteristics when using the same input data and {{WordCountMapperEmitPerValue}} code. In Infinispan 6, the performance is unaffected by cache value size, and the throughput increases as more nodes are added. The throughput in Infinispan 7 is affected when the value size is changed. Whether this is due to the input cache value size or intermediate values is to be determined. I can rerun the tests using the {{WordCountMapper}}, but I suspect that it will fail in Infinispan 6 due to the number of intermediate values emitted by the mapper. -- This message was sent by Atlassian JIRA (v6.2.3#6260)
