I've a pipeline embedded in a C++ app.
It previews a v4l src at 1080 and records it with a pulse src.

I've had stuttering issues in the past: prior to 1.18 it stuttered.
Using a 4xi7 (using 1.21) it works perfectly with htop and nmon showing 30ish% cpu usage.
Using a 2xi3 it sometimes plays perfectly, sometimes with a crackle every minute or so, sometimes stutters continuously.
In each case cpu usage is around 60%. nmon gives a hint with occasional clock-speed bursts to FSD.

How would I go about debugging this?

Are the RockRidge tools helpful and easy to understand ?
