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