And even if you fall under the first category, I find it hard to believe that the performance bottleneck is solved by using Vercel and SSR.

With all the other crazy shit people are doing (multi-megabyte bundle sizes, slow API calls with dozens of round-trips to the DB, etc) doing the basics of profiling, optimizing, simplifying seems like it'd get you much further than changing to a more complex architecture.
