H5 performance

I call an interface in a web page. I want to use performance to test the performance of this interface, but I don"t know how to get the data corresponding to this interface.

Mar.23,2021

through ResourceTiming api, the reason why I never get the data corresponding to the interface I want is that setResourceTimingBufferSize does not set a value for him.

MySQL Query : SELECT * FROM `codeshelper`.`v9_news` WHERE status=99 AND catid='6' ORDER BY rand() LIMIT 5
MySQL Error : Disk full (/tmp/#sql-temptable-64f5-1b3810a-2c0f1.MAI); waiting for someone to free some space... (errno: 28 "No space left on device")
