I suppose this can also play a part in the performance degradation I filed in an issue a bit earlier: * #38235

Could be related to: * #38267 * #38273

> @willemliufdmg Not sure if it could be relevant or not, but if you are using middleware, could you please remove or rename middleware.[js/ts] from the root of your project...

 This graph on Vercel itself also shows that the middleware for the demo app with the router bug is a lot slower than the blue one. I would expect...
