             Summary: IGFS: Investigate why BinaryMarshaller is slower than OptimizedMarshaller in meta operations.
                 Key: IGNITE-2836
                 URL: https://issues.apache.org/jira/browse/IGNITE-2836
             Project: Ignite
          Issue Type: Task
          Components: IGFS
    Affects Versions: 1.5.0.final
            Reporter: Vladimir Ozerov
             Fix For: 1.6


*Problem*
Running complex Hadoop tasks with default node settings typically shows worse performance than with explicitly set {{OptimziedMarshaller}}. Most probably it is caused by the fact that all our IGFS meta classes are Externalizable and hence cannot be handled by {{BinaryMarshaller}} out-of-the box.

*Solution*
1) Add all participating IGFS classes (IgniteUuid, IgfsFileInfo, IgfsBlockKey, IgfsListingEntry + all processors) to exclusions in static initializer of {{BinaryContext}}.
2) Mark all these classes as {{Binarylizable}} and implement writes/reads in raw mode.

Then check performance.
