The console is a character-based console device.

Generally when the standard stream are available, we have a console connection.

4 - Why Text to Console is slow

Why is stdout attached to the console so slow

  • The bytes have to be sent to the console application (should be quite fast)
  • Each char has to be rendered using (usually) a true type font (that's pretty slow)
  • The displayed area may have to be scrolled in order to append a new line to the visible area (best case: bit block transfer operation, worst case: re-rendering of the complete text area)
