> 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
