Eh, no. A rewrite is pretty much always better. You now know the problem you’re actually facing. Drop all the little wrong assumptions. And in general are better equipped than the last time.

I vaguely remember reading here about a company that slapped a backend together in Python. When they took off, the compute costs stung, so they rewrote in Go. Saved most of the bill. Some time later that started creaking, so they rewrote again. In Python, but managed to save most of the bill again.
