Maja Kabiljo created GIRAPH-357: ----------------------------------- Summary: Don't try to combine if there is only one message Key: GIRAPH-357 URL: https://issues.apache.org/jira/browse/GIRAPH-357 Project: Giraph Issue Type: Improvement Reporter: Maja Kabiljo
In SendMessageCache, we call combiner even if we have just one message. Combining is kind of expensive since we recreate the message object and the list. With default settings and bigger graph, for PageRankBenchmark there is 10-15% superstep speedup if we don't call it when we have a single message. -- This message is automatically generated by JIRA.
