Riccardo Russi (RRR69) added a comment to T68469: Mean crease interaction is very slow with subdiv modifier.

On 2.8 the playback of a shape animation or armature deform are very slow if we use the subdivision modifier. In Maya and Softimage but also the Blender 2.79 the speed is really much higher.
Slowness increases with detailed models with many vertices.
For realistic face and character animations having fast subdivision helps animators see animations in real time, at 24fps or higher. Opensubdiv allows this in many 3D software.
There was a 2014 video where Sergey showed an animated dragon with active and finally fast subdivisions. Now it seems to be back in 2013.
I think the increased performance of OpenSubDiv is a priority for modeling and animation.
