Filtering the execution trace based on the time taken for the method calls should show some interesting results.
根据方法调用所花的时间筛选执行踪迹会得出一些有趣的结果。
If the filtering happens in the application, there is no way of knowing how many rows to request, thus potentially leading to multiple calls to get a single page of data.
如果筛选在应用程序中进行，则无法知道请求了多少行，因此可能导致通过多次调用来获取单页数据的情况。
