I have performed some Androbench 5.0.1 benchmarks (default settings) on ext4 /data partition vs f2fs /data partition and found out that f2fs is much slower than ext4:
SR (MB/s) 470 160
SW (MB/s) 170 130
RR (IOPS) 39700 38600
RW (IOPS) 5600 3500
I wouldn’t expect such a difference, Is there anybody who can motivate this odd behavior?
