just a short followup - on mac "-noprefs" makes a huge difference!

thank you both for the answers, i am using the nogui tag since im building for a headless rpi, i will try to see if the noprefs makes a difference, i have a script that launches pd when my sound.target is reached on the rpi and it takes 4-5 seconds only when booting, if i start the script manually its almost instantaneous and no lag is present in linux so it might be actually related to something else

Pd sometimes seems to take several seconds to start up on MacOs. It once started up very quickly. I haven't figured out if this is a change in MacOs or in Pd.
And yes, the owing Pd instance has to wait for the sub-process to get running, so that will freeze it for a few seconds.
It migth help to clear out unneeded "libraries" (start the subprocess with -noprefs and explicitly add the ones you want). Also it will always speed things up to run the sub-process "-no-gui" whenever you don't need to see it.

<div>if the pd~ subprocess blocks (beyond the specified latency), then
the parent process blocks as well, so the behavior you describe is expected. It's simply not possible to spawn pd subprocesses in a realtime safe manner (yet).</div>

<div name="quoted-content"> <div>hey there, im experiencing a lag in my main patch when i
start a pd~ sub process. on my i7 quad core 16gb macbook pro its about 4-5 seconds until pd is running again and on an rpi 3 its about the same. is this a known thing? and if so, is there a workaround?
