>          Issue Type: Task
>          Components: interop
>    Affects Versions: ignite-1.5
>            Reporter: Pavel  Tupitsyn
>            Assignee: Pavel  Tupitsyn
>             Fix For: ignite-1.5
>
>
> Currently in .Net we:
> * write Guid and DateTime in Java format
> * calculate string hash code for field names with Java algorithm on each call
> Need to investigate if the following makes sense:
> 1) In .Net always write Guid and DateTime in native .Net format as fast as 
> possible; Make Java understand that format. (Not every Guid written in .Net 
> will be read in Java, so we can win time).
> 2) Cache string hashcodes somehow.
