> In SsgNetworkMemoryCalculationUtils#enrichNetworkMemory, getting PartitionTypes is run in a separate loop, which is not friendly to performance.  If we want to add inputPartitionTypes in the subsequential PR, a new separate loop may be introduced too, which I think is not a good choice.
> Using a separate loop to get each collection just looks simpler in code style, but it will affect the performance. We can get all the results of maxSubpartitionNums and partitionTypes through one loop instead of multiple loops, which will be faster. In this way, when we need to add inputPartitionTypes later, we do not need to add a new loop logic.
