in reply to How to disable buffering ?

well said by lakshmananindia ++

Why do you do select everytime on filehandles and then set $| to true, that is not a good idea
you can use IO::Handle or FileHandle modules to open the files and set autoflush on that handle to true, that will avoid using select everytime on different handles and setting $|=1

Instead of flushing the buffer can't we disable the buffering itself ?
buffering is our friend, saves a lot of time for us, so don't think our disabling buffering
