Xiaomi Mi A2 slow Memory

[Android Central Question]

I have an Xiaomi Mi A2 and I make an benchmark with Antutu, finaly score was 130.000 point. But Memory score was 5652 point, is very slow. On Youtube I view that other user obtain 7500 - 8000 point. I have V9.6.10.0.ODIMIFE firmware. This is an hardware problem or is software (I think that is hardware)? Sorry for my bad english.
