> GridCacheProcessor#restorePartitionStates method tries to employ striped pool to restore partition states in parallel but level of parallelization is down only to cache group per thread.
> It is not enough and not utilizes resources effectively in case of one cache group much bigger than the others.
> We need to parallel restore process down to individual partitions to get the most from the available resources and speed up node startup.
