File_get_contents vs readfile speed

readfile vs file_get_contents SPEED 
(SIMILAR IF YOU DON'T ECHO THE RESULTS)

1) readfile()
will read the file directly into the output buffer
  
2) file_get_contents() will load the file into memory, 
ONLY if you echo the result IT WILL BE COPYING from memory to the output buffer 
using 2 times the memory of readfile().
