Buffering is used by Perl for efficiency reasons.

System calls are always expensive, and to reduce that we need buffering.

It is always good to flush the buffering, instead of removing the buffering itself.

In Perl, you can't turn the buffering off and it is stated in Suffering from Buffering

The great pleasure in my life is doing what people say you cannot do.
