Blendshapes

Every time a blendshape changes, the vertices have to be retransformed on the entire mesh. [1] If the majority of the mesh is not part of any blendshape, then that performance is wasted. Neos can automatically optimize this with the "Separate parts of mesh unaffected by blendshapes" found under the SkinnedMeshRenderer component. Whether this is worth it or not varies on a case-by-case basis, so you'll have to test your before/after performance while driving blendshapes to be sure.
