Hmmm, yes, realtime is fixed now?? (it was returning hardwired 
priorities (!) and was generally a mess). But part of the problem is 
rtkit itself which will not let you do what you need to do if you know 
what you are doing. Maybe now not using rtkit works fine.

I did a quick test last week and the results with ardour were bad (up to 
date Fedora 34), for a complex session it would hang forever or crash.

And I have seen a big difference when using jacktrip - pipewire triggers 
long dropouts when new clients connect, jackd is fine. So I suspect it 
has (had?) long delays when compared to jackd when reordering the graph 
when new clients connect or new ports get created. I still have to try 
to debug this to get more data, time time time...

Yup...
(but so far for production I have to use jackd)
