Hi, we are using S32ds for development using  MPC5777C . However the default settings are running overall system slower than expected. I would like to understand the options we can use to optimize the for performance. I need compiler and build system related optimization options focusing on following points.

1. Usage of SPE instructions

2. Usage of VLE 

3. Reducing volatile context switch timings (usage of APU)

4. Fast ISR execution and thus settings for low latency interrupts.

5. Usage of floating point instructions in optimized way.
