I have systemd on ten or so machines, all of them doing quite
intensive audio work, and have no problems at all with it. 
All these machines run Archlinux, the default setup limits
RT use to 95%. 

Apart from that, I'd agree that systemd was a nice idea but
has grown into a bigger problem than whatever it tried to
solve. The comment by another poster was exactly to the point:
systemd defines policy while it should only provide methods
to implement policies.

and hysterically inflated market opportunities. (Cory Doctorow)
