-------------------------------------
Resolution: Fixed
> 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
> Assignee: 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.
