Question?
1: Is every access compiled a waste of CPU?
The compilation file exists, so you do not need to introduce it directly during compilation.
2: After the template file is modified, it must be re-compiled.
When the modification time of the template file exceeds the modification time of the compilation file, it indicates that the template file has been modified,
Therefore, recompile the template file.
