Pavel Voronkin commented on IGNITE-9870:
----------------------------------------
We can parallelize each marshall and zip of "parts", "partCntrs", "partCntrs2",
"partHistSuppliers" and "partsToReload" in a separate task in thread pool and
speed up message preparation.
> GridDhtPartitionsFullMessage#prepareMarshal compression parallelization.
