-----------------------------------

             Summary: Remove timers for compute method
                 Key: GIRAPH-900
                 URL: https://issues.apache.org/jira/browse/GIRAPH-900
             Project: Giraph
          Issue Type: Improvement
            Reporter: Maja Kabiljo
            Assignee: Maja Kabiljo
             Fix For: 1.1.0


When processing on a single vertex is quick, having timers around each compute call is very
expensive - in some experiments supersteps run up to 40% faster without this timer. I never
found it useful since average times are usually short enough to not mean much, and also it's
not just user code time but when we block on sending requests it's counted here as well. So
I'm just removing it instead of making it optional.
