Saving multiple files takes several minutes

A couple years ago I built a dialogue editor in graphview by following this tutorial. I didn’t have much tools experience at the time and didn’t really understand most of it, but it worked great, with one exception that is really biting me now. Whenever I save a graph, it saves each node out as a separate file. They’re very small, usually just 1k. But once a graph gets sizable (50 or so nodes) this operation starts to take forever. 30+ minutes. My suspicion is that Unity is doing its full asset-validation pass after each file change. My hope is that there’s some sort of way to disable that during these operations. A checkbox that tells Unity to stop worrying about the projects file directories until I tell it to again.

If anyone has any advice regarding this, I would be extremely grateful.
