HW CRC slow?

Are there any benchmark reports about CRC peripheral speed and performances on the S32K11x mcu?

I need to check the integrity of the whole flash memory at the startup and in my opinion it takes *a lot* of time.

At 24MHz core speed with 32bit writes instead of 8 I measure 15ms for 128KB of memory.

I am using the core to load data; i can imagine that DMA could speed up computation but I don't know how much. 

Any suggestions or best practices to speed up the crc computation?
