Vladimir Ozerov commented on IGNITE-1962:
-----------------------------------------
Gives +10-20% to write throughput in case of Binarizable. But hard to implement
and require very thorough testing. Hence, moving to 1.6.
> Binary writer: implement speculative field ID guessing.

>
> Field ID calculation with deafult ID mapper is relatively costly operation.
> It can be avoided in most cases if we implement a kind of table for
> speculative guessing. It will track performed write "tracks" and do it's best
> to avoid ID mapper call.
> We already have this tecnique in .NET and it shown pretty good marshlling
> perf improvement.
