using KSDK 1.1, KDS 2.0.0 with a FRDM-K64F.
Project Bare metal (no rtos).
I've implemented a data logger, and it works.
Now I'm trying to improve the performances and in ffconf.h there is this #define _FS_ENABLE_THROUGHPUT_OPTIMIZATION.
If I set it to 1 the fatfs will use 2 sector as buffer to write to the SDHC.
If I set it to 2 I can decide how big will be the buffer (2-8 sectors).
So the question is:
somebody has already done some test/benchmark/... with this _FS_ENABLE_THROUGHPUT_OPTIMIZATION?
Pro/cons on setting it to 0, 1 or 2?
