CMSIS-RTOS time slice: Is any way to use ticks or microseconds

Hi, I want to use STM32427 instead of STM32407, but uVision V4 doesn't supports that chip. So I upgrade uVision from V4 to V5, and plan to use CMSIS-RTOS RTX instead of RTX. But now I have some...

flush_cache_all() API consuming 200+ microseconds.

Is this is normal behavior? Or suggest any other alternative. Since flush_cache_all() consuming major portion of total execution time, I couldn't proceed with this. Is there any other way, which helps...
