> .NET: Improve DataStreamer performance
> --------------------------------------
>
> Key: IGNITE-2874
> URL: https://issues.apache.org/jira/browse/IGNITE-2874
> Project: Ignite
> Issue Type: Improvement
> Components: platforms
> Affects Versions: 1.6
> Reporter: Pavel Tupitsyn
> Assignee: Pavel Tupitsyn
> Priority: Critical
> Fix For: 1.6
>
>
> DataStreamerExample takes ~50s to load 500K accounts, which is quite slow.
> Quick profiling shows that DataStreamerBatch.Send spends a lot of time in
> ReaderWriterLockSlim and GC. Only 13% is actual Java interop.
> Considerations:
> * Data streamer is mostly used from a single thread
> * Try to replace ReaderWriterLockSlim with simple lock, this can be faster
> * Try to reduce allocations
