bq.Oh only one DN? I haven't tested this scenario before. In general, 
AsyncFSWAL will have a lower latency if you write to more than 1 DN as it sends 
the data to multiple DNs concurrently.
True. That is why I just asked if 1 DN is not the right way to check this out. 
I have profile reports. I can attach here if you want to have a look.
