> If you want more speed-ups, you should consider whether you can do better than the standard `svd` .

For data with only 3 dimensions I think it will be hard to make it faster, otherwise truncated svd or RandomizedLinAlg might be worth a try. Using MKL and `Float32` instead of `Float64` can speed up svd quite a bit.
