With the current values the snapshot on gmail requires about 27sec. This operation could be 30 times faster if we increase the chunk size from 100 items to 10000. Also very long strings will significantly affect the transfer size.

sizeof(int) * 10000 * nodeFieldCount = 200kb sizeof(int) * 10000 * edgeFieldCount = 120kb sizeof(int) * 10000 * idMapEntryFieldCount = 80kb sizeof(String) * 1000 = 80kb So the expected working set for the serializer is ~480kb
