Whats the speed in kbit/s for the printf Command? I am using a Stratix III Board(NIOS II CPU).

The question is unanswerable as it depends on too many outside factors such as:

1 - Processor speed

2 - What is the STDOUT device and it's speed

3 - What other things is the processor busy doing.

Even knowing those numbers nobody is going to be able to estimate it for you. You'll just need to run some tests and measure it for your system.

Relatively speaking, printf is slow.
