Vladimir Ozerov created IGNITE-2316:
---------------------------------------

             Summary: Replace GridSpinBusyLock with improved version of GridStripedSpinBusyLock
                 Key: IGNITE-2316
                 URL: https://issues.apache.org/jira/browse/IGNITE-2316
             Project: Ignite
          Issue Type: Task
          Components: general
    Affects Versions: ignite-1.4
            Reporter: Vladimir Ozerov
            Assignee: Vladimir Ozerov
             Fix For: 1.6


1) GridStripedSpinBusyLock is not striped properly at the moment - produced AtomicIntegers are located too close to each other to produce considerable amount of false-shares. To fix it, int state of each lock should be padded with dummy values. This will give significant throughput increase.
2) Then GridSpingBusyLock must be replaced with GridStripedSpinBusyLock all over the project.
