It's faster on my 2018 well-above-base-config Macbook, too. Somewhere along the way the original promise of this whole AJAX thing—faster updates, no page loads—got lost. The page loads are usually faster for real sites in the wild, where we have two versions to compare.

I use it everywhere now. It loads instantly, it's amazing. The only thing I miss is the auto categorization, I have to filter out all the newsletters with my brain now.

You can also setup filters which are easy to do in gmail and work better than autocategorization.

I'm tempted to make the switch myself, is there a way to permanently force this? Otherwise I'm just going to use Gmail from Thunderbird, which can be a Behemoth but it's not as damn slow as that UI at the end of the day.
