I often have ~100 tabs open, and I have a habit of hitting ctrl-tab and letting it cycle as a fidget. The first cycle is not smooth because there's noticeable aggregate loading, but it's able to cope just fine after with a lot of tabs completely loaded. This has improved a lot rather recently. And when I click a lazy loaded tab after startup there's no noticeable load for the individual tab, it's right there when I click it. It's only when you force-load all the tabs that load times become visible, but that's to be expected.
