NSTextView Performance May Degrade for Large Plain Text Documents When usesFontPanel Is Active
I was profiling performance bottlenecks in the The Archive and noticed that no matter how much highlighting functionality I removed/commented-out, the apparent slowness was all due to … Touch Bar API?! I have been “pruning” the Touch Bar related calls from the profiling stack to focus on what I though would be the real bottlenecks. But, as often, it turns out this was stupid and the instruments did point out the true problem. Something indeed was causing trouble here, it turned out.
