             Summary: [HLC] Performance microbenchmarks
                 Key: HBASE-18542
                 URL: https://issues.apache.org/jira/browse/HBASE-18542
             Project: HBase
          Issue Type: Sub-task
            Reporter: Appy


Need tests to benchmark performance of Clock#now() and update() functions (for all types of clocks).
If update() is too costly, we can do optimizations in ExecuteProceduresRemoteCall#call() and other places where we call update() in loop. Instead, it might be faster to calculate max timestamp in loop and call update() just once.
