printf very slow while Semihosting + Eclipse + OpenOCD on STM32F429

I am trying to do semihosting, so that I can print debug messages to the console on Eclipse + OpenOCD.
It works except that the printf s take a long time to print. For example if I want to print "Hello World". It prints 'H', then .5 seconds later it prints 'e', another .5seconds, then 'l', and so on.

Does anyone know how to fix this?
