Summary: .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
