The homepage is about 3KB and was tested locally

Copy the code The code is as follows:

file_get_contents('shadow.xml ');

Took 0.0003 seconds

Copy code The code is as follows:

$indexFile = fopen('shadow.xml', 'r');while ( !feof($indexFile)) fgetc( $indexFile);

Took 0.026 seconds

Copy code The code is as follows:

$indexFile = fopen('shadow.xml', 'r');fread($indexFile, 10000);

It took 0.0003 seconds

I guess all the time is lost in the while loop or something.
