Optimize Boot time of my Buildroot

I have a working buildroot configuration for Raspberry Pi3 that compiles my programm (with QT5.9 ) and boots automatically at startup .

Cold boot time is currently 17 seconds on a class 10 SD card .

I would need someone to optimize my buildroot configuration to boot in less than 5 seconds into my program and maybe display a fullyscreen picture at startup until the programm is booted ( optional)

Here is my buildroot repository
