Yep,

The optimization of sharing identical vertices with the same material cannot be used when you have bones.  There is no guarantee these have the same bone influencers.  The number of vertices is usually higher than if you deleted the armature.

 

The real killer is each vertex group of these vertices must be checked against each bone to see if it a match.  The result the compute time explodes as number of bones and vertices get large.
