CPU spikes due to Auto Save in Bitwig

xard-dev commented 6 months ago

I can reproduce this issue in Linux and Ardour 8.1 and Ardour 8.2.

I had to disable auto saving due to heavy CPU usage when having 16 instances of Vaporizer2 on the same project: the project file size grows to around 36 MiB and every time the project is saved the DSP usage jumps up to 100% for couple of seconds stopping all audio.

Yes, I could reproduce it. See the spike below that happnes exactly every 60 seconds:

Bitwig seems to call getStateInformation() every other minute.
