printf very slow! - CW10.2 - K10

Is anyone else using printf to send debug data to the Console window? I just started doing this and noticed that it is REALLY SLOW!

 

I can literally watch it draw one character after another. How can this be if my MCU is running at 100MHz?

Is the interface backwards through my debugger just that slow?

Same problem here, I was just about to open a thread myself....

 

I'm using CW10.2 with a Kwikstik and printf is just slow. But it's not just on the CW-side, I noticed that using printf blocks the MCU until the output appears on the console in CW.
