That’s not the point. And the 1k req/s is a made up number in this case. The point is that SQLite is a single process or at best a single process group if you implement locking. It’s not about performance. I wouldn’t be surprised if SQLite is faster for writes than Postgres, being simpler. The point is that one is a really good bicycle and another is a really good all terrain truck. Both have uses and for a certain type of getting from A to B there is overlap in their utility but they have different use cases.
