Micrologics' SQLite production guide ships the full pragma set without a single benchmark
Micrologics lays out SQLite as a primary store through a copyable pragma checklist: journal_mode = WAL with synchronous = NORMAL to cut fsync cost, busy_timeout = 5000 plus BEGIN IMMEDIATE to avoid deadlocks under the single-writer constraint, and cache_size = -64000 for 64MB of page cache. The claims wrapped around it — sub-millisecond reads, hundreds of concurrent requests, millions of queries a day — arrive with no latency or throughput measurements and no comparison against Postgres. The config is copyable today for a single-node server where the network hop to a client-server database is the dominant cost, but the ceiling has to be measured per workload.

By running SQLite directly within the application process on the same server, you eliminate the network overhead entirely.
Why this matters
- → Local storage eliminates network roundtrips — the primary bottleneck in traditional databases.
- → Single-writer constraint and SQLITE_BUSY errors require explicit concurrency handling.
- → No latency measurements provided; claims need per-workload validation.
