Recently, we hope to have a local response as fast as possible. The results show that MapX is very slow in processing. Therefore, insert the trace between statements Code, Accurate to millisecond-level comparison, the results show that the problem lies in the processing of MapX.
You don't need to think about feature update. It must be slow. However, it is still slow after the update is blocked. It is found that even when layer. Search is used, it is also very slow. Almost 20 ms to 30 ms. Because there are many positioning operations, the overall speed is dragged down.
