unpatch: slow loading of remote sessions #41

Open reduzent opened 2 years ago

On macOS and Windows, syncing from a peer can take quite some amount of time - up to a few minutes, depending on the size of the session, the number of instruments and effects used in the session, respectively. The issue is less pronounced on Linux, it seems.

It looks like the repeated computation of the DSP graph takes a lot of CPU time. When turning DSP off during session loading, the loading time is significantly shortened.

BTW: Loading is only slow when joining an already running session. Unpatch loads all instruments within one DSP-off-on cycle, but each of the instruments may cause further DSP-off-on cycles, which take more time the more stuff is loaded.

When loading a preset, DSP is until all is loaded and thus loading from preset takes significantly less time.
