Meh, if it's all just symbols it's probably not that helpful.
I've summarized your results here:
1 concurrent 4k write (libaio, direct=1, iodepth=1)
IOPS Latency
wb on wb off wb on wb off
dumpling 10870 536 ~100us ~2ms
firefly 10350 525 ~100us ~2ms
So in single op tests dumpling and firefly are far closer. Now let's
see each of these cases with iodepth=32 (still 1 thread for now).
