Under the same condition, I checked the number of read operations and write
operations to EBS.

I never call GET API of RiakKV but, VolumeReaOps(Orange line) rapidly grows.
The following graph is VolumeReaOps vs VolumeReadBytes.

VolumeReaOps grows but VolumeReadBytes stills low.
What happens to RiakKV? RAM size is too small?
