On one of my site, I have a large-file download method using:
then PHP file executes
readfile to start file downloading.
Typically, not to go in details of load-balancing, I just wanted to know how PHP engine works - does such approach in PHP (throwing files using
file_get_contents or etc...) take more CPU/Overload, compared to downloading with direct links, like
site.com/MyLargeFile.mp3? Or PHP engine does same using those commands?
