Just a quick reminder that already, our noise source is known to be pretty slow, which prompted the fast_noise_source (which precaches some random data and reuses that). So, when you need maximum entropy, you use the slow one and if you just want some AWGN you use the fast one. Unless the load is significantly higher, I'd say we rather want better randomness than faster noise sources -- and the fast noise source will stay unaffected anyway.
