Significance of The technical settings for the table Size Category for Active Table of DSO

Hello Experts,

what is the Significance of The technical settings for the table Size Category for Active Table of DSO, currently we are having setting as Size Category
='4' (Data records expected: 40,000 to 160,000), what difference it will make if i change this setting to Size Category = '7' (650,000 to 1,300,000 data
records).

My current data records in this DSO are around 1.7 Million. this DSO is getting looked up in one of the start routine code.

I need to know what is the Significance of changing the size category. will this change improve in data load performance?

Thanks & Regards,
