Worth noting is that there is a v2 branch of Ogre, which is a near-full rewrite aimed at fixing these issues [1]. It was, I think, more than 5 years ago that Matias Goldberg wrote the first demo of what speedups are possible in Ogre by following a data-oriented approach: contiguous structures, eliminating excessive branching, structure-of-arrays layouts, etc. I'm happy it's grown into something pretty usable today (from what I see). Now it seems that all this is the standard industry wisdom, but I feel like at the time people were only slowly realizing the real cost of all those vtable lookups and abstractions.
