I just tested this in firefox on ubuntu. Three subsequent new tab tests.
Load: 4.34s, 5.14, 2.96, 3.35
DOMContentLoaded: 3.65s, 4.56, 2.92, 3.33
Finish: 13.14s, 10.77, 8.49, 12.02
So it's getting a bit faster over time, but still heinous, and crucially, it isn't hanging on requests. Individual asset GET/POST requests are taking tens of ms, worst was a few parallel 254ms GETs on a cold start. Usually 50-70ms. But there is a flurry of requests, then a period of very few requests until 5s after init, then another flurry.
Same OS, chrome 115.0.5790.170, no blockers, youtube is much snappier, it still definitely takes a few seconds to paint thumbnails, but it's basically done by 5s.
