stm3210c-eval and lcd

Hi,
I use a stm3210c-eval board. I connect to the lcd display through the spi interface with the help of the st gui library.
I find the display very slow. To display a 16 bits rgb picture of 152x152px, it takes almost one second to transfer and refresh.
The library first set a proper window and then write to the lcd gram the 152x152 bytes consecutively.
152x152x16/9MHz=40ms which would be to fast to notice.
What is wrong?
