A recipe for improving SQLite concurrent write performance:

1. PRAGMA journal_mode=WAL;
2. PRAGMA busy_timeout=5000; or higher.
3. PRAGMA synchronous=NORMAL;
4. Keep write transactions small.
5. Avoid write-after-read transactions.
6. Use app-level locking if needed.
SQLite concurrent writes and "database is locked" errors
SQLite claims to be one of the most popular pieces of software in the world, being integrated into every major operating system and browser. It...

Yes! a 15-min-read post to catch up on all experiments, reproductions, explorations around DeepSeek R1

We've summarized everything we did & saw in this first week since DS came to light

Results/code/dataset/experiment => if we missed one, share & we'll update

There is nothing easier than writing something you want to write, and nothing harder than writing something you don't want to write.

SQLite can give you an excellent write performance, e.g. ~70k inserts/s. Concurrent writes are ok, but if you have too much concurrency, performance drops, e.g. with 128 threads inserting, it's ~3k inserts/s . There's a trick: use a mutex to sync threads, same 128 threads give ~50k inserts/s.
