Problem to reach high Frequency on GPIO

i'm using stm32 nucleo board. The oscillator is configured to 32MHz speed.
Now, if i use the easy following code in the main:



   HAL_GPIO_WritePin(LD2_GPIO_Port, LD2_Pin, 1);
   HAL_GPIO_WritePin(LD2_GPIO_Port, LD2_Pin, 0);



the frequency i measure on the LD2 pin is only 750KHz. This is really strange, i expect
to run more quick than 750KHz only.


Can someone help me?
