Performance Comparison between insert into and insert into select

It's okay today. I tested the performance of insert into and insert into select. I didn't expect these two performance differences to be so big.

USE insert into table (field ,...) values (value ,...), insert into table (field ,...) values (value ,...)... status

 

USE insert into table (field ,...) select (value ,...) union all select (value ,...) union all select (value ,...)... status

The data I inserted at a time is 1190. The time used for insert into lingers in 510 milliseconds, while the time used for insert into select lingers in 16 milliseconds.
