I agree. If algorithms are slow, it doesn't matter as long as they are fast enough. You should not spend time prematurely optimizing for performance that you don't need, if you can more easily use caching to give you real, experienced performance. If you want to optimize uncached performance you can turn off cache in a development/staging environment. If you run a website that is in business do not give your visitors bad performance (uncached) on purpose.
