[PD] os x realtime not under root.

[Hans-Christoph Steiner]

Its not necessarily slower, since it doesn't change the CPU.  This just 
allows you to use the -realtime flag, which gives Pd elevated execution 
priority on the CPU.  This means that it is harder to interrupt Pd and 
it will be allowed to use more of the CPU time.  IMHO, I think this 
mostly affects dropouts and glitches, since Pd won't be interrupted as 
often by other processes (Aqua being a likely culprit since it uses a 
lot of CPU and runs at an elevated priority).  But its possible that it 
could speed things up a little bit.
