-----------------------------------
Issue Type: Improvement (was: Task)
> .NET: Optimize writes of ultra-dense structures
> -----------------------------------------------
>
> Key: IGNITE-1421
> URL: https://issues.apache.org/jira/browse/IGNITE-1421
> Project: Ignite
> Issue Type: Improvement
> Components: platforms
> Affects Versions: 1.1.4
> Reporter: Vladimir Ozerov
> Labels: .net
> Fix For: 2.0
>
>
> There is a case when we can dramatically increase marshal/unmarshal
> performance:
> 1) Type is a structure;
> 2) It contains only integer/float/double primitive types with well-defined;
> memory layout which is consistent with our serialization protocol;
> 3) We are sure that there are no gaps in it's memory layout.
> 4) User writes it as "marshal-aware" and fields write order is consistent
> with memory layout.
> In this case we can copy the whole structure into our stream with a single
> memcpy() operation. And we can read it from the stream as easy as [pointer
> dereference + position shift] (provided that target is on the stack).
> We should also disable handles for structs, since it does not make sense.
