KL46Z FRDM internal flash using

I am using KL46Z FRDM board and I want to use internal flash to store data through FTFA commands. I am able to erase blocks and program longWords (4 bytes). The problem is about timing : it takes long time in each Program longword before CCIF flag is set (around 176us while datasheet KL46P121M48SF4.pdf says 65 us) so it takes around 500ms to program 32 KB.

Did someone experience same problem? Writing data 32 bits by 32 bits is the best way?

Thanks for your help
