I have replicated this by cmd-tab'ing to a cold app window. But if I just tab between say messages and firefox, I can't detect even the tiniest pause. If I click on a new tab in firefox, I see the tab add button color change instantly even if the tab takes 50ms to open.
On my beast Win10 machine, everything is also instant, it's just randomly throughout the day, it will lock up while tabbing to an app or something for 10 seconds.....which is just so weird and annoying. CPU shows it is pegging a thread for the opening app, doing who knows what.
