> .Net: Optimize handle registry.
> -------------------------------
>
> Key: IGNITE-1415
> URL: https://issues.apache.org/jira/browse/IGNITE-1415
> Project: Ignite
> Issue Type: Task
> Components: platforms
> Affects Versions: 1.1.4
> Reporter: Vladimir Ozerov
> Priority: Critical
> Labels: .net
>
> The main problem with handle registry is CAS on a single shared variable.
> This could result in a very bad performance under contention.
> Several techniques can be applied here:
> 1) Stripes. Assign some ID to a thread and then use it to pick correct stripe
> for the thread. Be careful with false-sharing effects as stripes can be
> located very close to each other.
> 2) Cleanup with relaxed membars. When we are to remove the handle, no need
> for full HB semantics. We are ok if subsequent calls to the same handle will
> see not-killed object for a while.
