On the other hand, I've found that a lot of the caching that happens organically from each component building up it's own state of the world can lead to poor performance of its own. You often end up reading single values from random places in memory.

You can often optimize a single, large state transformation by utilizing that it does a lot of similiar work. You can also often get a big performance boost by batching up computations.

Half of all performance problems are solved by introducing a cache. The other half is solved by removing one.
