Todd Lipcon created HBASE-5915:
----------------------------------

             Summary: Improve performance of KeyValue comparison
                 Key: HBASE-5915
                 URL: https://issues.apache.org/jira/browse/HBASE-5915
             Project: HBase
          Issue Type: Improvement
          Components: performance
    Affects Versions: 0.94.1
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon


Got bored tonight and poked around at making KeyValue comparison faster. I was able to get
a ~23% speedup on a micro-benchmark I wrote by using Unsafe in a few more places. This should
make some difference for real workloads, since this is usually one of the top CPU consumers.
