Good morning, Myrrix provides a Recommender that implements a specific recommendation algorithm based on matrix factorization, which is generally efficient in most cases. However, depending on your data and access pattern, it may be better to use Mahout as well, as it provides many different Recommenders. So you can evaluate each implementation and use the recommender that the given time best suits your dataset.
