Desktop cold-start got faster
On 2026-09-07, Lauren Tan (@poteto) posted that the Grok Bot desktop app got faster after a week of perf work.
She reported these cold-start gains (author-reported from that post):
- usable shell: -247ms / 18%
- LCP: -425ms / 23%
- FCP: -234ms / 16%
Elon Musk retweeted the same post that morning, which is how a lot of readers will see it.
That is a desktop app story. Open the app cold and you should feel a snappier path to a usable shell. Soft-hedge the numbers: they come from Lauren’s post, not from an independent lab run on this desk. Plan gates and your own machine still set what you feel.
If you already run heavy coding on a Desk farm path, keep that habit. Faster cold start helps the app open; it does not change where deep multi-file work belongs.
