I wanted to confirm that I also find that Ceph Jewel (10.2.0) on Xenial
feels considerably slower than Ceph Infernals (9.2.0) felt on Trusty. I
used to regularly sustain reads/writes of 90 MB/s from my desktop to my
Ceph cluster, and now normally sustain 50 MB/s, maybe spiking to 85 MB/s.

Hi Florian,
All the benchmarks were run on strictly identical hardware setups per node.
Clusters differ slightly in sizes (infernalis vs jewel) but nodes and OSDs are
