I read that a real time kernel would be quite useful on a raspberry pi for pure data, and I wonder if this project would help:

I am not too much versed in the whole RT world so I am downloading it now and will see how puredata runs on it

Hi,
Have you tried different RAM settings? One can change the share of RAM allocated to the CPU versus GPU, and I'm assuming that this would make a lot of difference in the performances of Pd. I'll give it a shot tonight.
Cheers,
Pierre.

Maybe there's a confusion between real-time priority (standard kernel) and hard real-time (RT kernel).
Hard real-time is more for really time-critical stuff down to microseconds, like driving a CNC or stuff. Having a real-time task running can feel like your computer is super-slow. It's more made for single task processing.
As far as pd is concerned, I'd say real-time priority is enough, and is configured with /etc/security/limits.conf.
