System optimizations?

[swizzle]

The other advantage of rt (or isolating cores as mentioned earlier in the thread, which accomplishes much the same thing) is it reduces the likelihood that other processes will interrupt the audio rendering thread which could increase jitter (a slightly time-misaligned audio frame). That doesn’t usually manifest as missing samples but as the music not sounding as accurate as it otherwise would (and lack of accuracy is usually expressed as it not sounding natural). MPD moving to some processes being rt is a welcome move and should have moode sounding better than ever even without config file hacking.
