setData 性能问题，一次性设置几百条数据，大小 400kb 以上，可有性能优化方案？SetData performance problem, set hundreds of data at a time, the size is more than 400kb, is there a performance optimization plan?

There may be hundreds of item data in the customer's shopping cart, and the data size is about 400 KB after json.stringify. SetData is too laggy to view layer at this time, which will cause white screen in about 2 seconds. The problem clearly indicates that the data cannot be paged, that is, hundreds of data on the interface are returned at one time. My temporary solution is to intercept the first 10 SetData to solve the white screen problem, and then assign the overall data SetData after setTimeout for 50 milliseconds. The white screen problem in the above scheme is solved, but there will be 10 pieces of data loaded first. At this time, when sliding the screen, it will not slide for a second or two (it is stuck because the next SetData is assigning all data). I saw that SetData does not have a push function. I wanted to split SetData several times in a loop. Do you have any similar experience or better scheme? Thank you very much!!!
