Scaling SQLite to 4M QPS on a Single Server (EC2 vs. Bare Metal)
In this technical retrospective (2018), @quinthar shares practical architectural lessons learned from running, scaling, or migrating production software under lean constraints.
Core Principles for Independent Builders:
Defaulting to simpler architectures (such as monolithic frameworks, SQLite, or managed VPS) prevents early engineering bankruptcy.
Evaluating true compute and egress costs reveals that high cloud bills can often be slashed by 80%+ through judicious re-platforming.
Code you write at 2 AM as a solo engineer must be easy to debug six months later without complex microservice dependencies.
Community Debate Themes:
HN engineers debated the tradeoffs between cloud convenience and raw server economics, database indexing strategies, and resisting premature architectural complexity.

There's a few things that stood out to me that seem like "bad practices":
This seems very odd and redundant. Does someone manually edit all servers when a new server comes online?
Why would you use random if you want determinism? That sounds like the opposite of random to me.
Was this blog post really written by the founder!?!
The perftest[0] code is in a branch named "dbarrett_perftest" but that still surprises me.
