In the visual map project, there are several interfaces that are slow to load, about 16S. The first loading is nearly one minute. Who can stand it?

Compared to the formal environment and the test environment, this interface has the same amount of data, but is slower on the test server, excluding scrolling plug-ins and other influences. Annotate the request and then the front-end data initialization logic to determine whether it is a back-end interface problem or a component rendering problem.

Finally, it was traced to domain name resolution. Change the domain name of the test server into IP address directly, save the process of parsing good, 40ms load the whole web page.

ok.
