Another possibility is that your UART driver/hardware configuration
(cache misconfiguration?) is not seeing the UART "Tx ready" flag
properly so that every time a character is sent to the UART it polls the
UART flag for the maximum time, making the serial output extremely slow.

No hardware knowledge, just speculating...
