Please put a note in your article explaining this. SQLite is literally 10x faster using the WAL vs standard mode. And while you're at it, please consider an index on the SQL server and SQLite tables, so the reads are faster as well.

I would love to see the article updated using SQLite's PRAGMA journal_mode = WAL and PRAGMA synchronous = NORMAL. Then it would be a much more fair comparison.

Please don't give programmers a license to be lazy and not learn about their tools!!! If this article is trying to inform, or give benchmarks, it should not come to invalid conclusions without explaining the tradeoffs.
