React Router 7 is too slow on Cloudflare Worker

[cwagner22]

If I deploy a simple example app I get about 110ms TTFB.
If I add more routes, with added third party libraries increasing my server.js bundle size to about 1.5MB, TTFB takes about 600ms.
(even for the same route)
Why is there such a big difference?

The issue is due to Cloudflare workers' cold start nature. I recommend you test it on a dedicated server like Railways.app
