We have some clusters using overlay2 and some using devicemapper (lvm). We haven't noticed much difference in terms of performance. I will admit though that disk performance isn't really something we're very focused on, so take my observation with a grain of salt.
We are now opting more for using overlay2 though. Our reasons being that monitoring capacity with devicemapper is less transparent and changing the capacity is a more complex process with devicemapper than with overlay2. Supposedly disk caching and disk space usage is also more efficient with overlay2. Gr.
