Have an aspx page, left, upper right, lower right, three kind of frame structure, the left side menu, up and down on the right shows the corresponding content, one on the left menu point now, after the right side shows special slow, takes five minutes to show, like how to troubleshoot this problem? Is there any way to check the point after the menu on the left, the background is for what operation? Are doing? Lead to the right shows so slow? I think of, but not the page displayed priority and other operations can delay the delay, can omit the ellipsis, can slowly slowly to the background of operation in the background, to show the first page to the somebody else see? How to solve this type of problem?

Also met this problem before, behind screening because returns the content of image problems, image storage is binary stream, lead to the content of the return is very large, which affects page loading slowly, you can see if the problem

CodePudding user response:

First, F12 debugging looking is what long timescales
Second, see page architecture, if instead of div + CSS table too much this image can affect the speed of the whole page rendering
Third, because the requested data is too large, lead to page rendering time is too long
Fourth, because the data of the slow query result in

Because what you have said is just a single page time consuming, well check
According to the above method for screening is very simple
