To look at our company, we have decided that our upcoming application release is mostly dedicated to performance optimizations rather than new functionality. This was something we felt was needed and also was requested by some clients.
Therefore we have spent a lot of time identifying performance bottlenecks in our app and reviewing code and refactoring it to make things run faster.
So in our case we did it because management approved us doing it for this new release, because we showed to them how much performance improvement could be gained.
