Subject [jira] [Created] (IGNITE-2874) .NET: Improve DataStreamer performance
Date Tue, 22 Mar 2016 09:09:25 GMT
Pavel Tupitsyn created IGNITE-2874:

             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.

* Data streamer is mostly used from a single thread
* Try to replace ReaderWriterLockSlim with simple lock, this can be faster
* Try to reduce allocations
