There is a kind of speed called Turtle line, there is a kind of feeling called unbearable, there is a kind of desire called performance improvement, there is a kind of difficulty called the bottleneck. Everyone wants their programs to run quickly, but how hard it is to improve performance is, even getting started. Which of the following is the key to performance improvement? Which segment is the bottleneck of the program running? Do you have to add a period of output before and after each funct

Profiler. For example, suppose there is a database demo, and the demo contains a data table tab_demo. Its structure is as follows: Run the "SELECT * FROM tab_demo;" command to query all records in the table. The following result is returned: The following describes how to use Profiler to view the above database operations. Run the "SHOW profiles;" command to return the time spent in each operation ,:
