The article examines how SQLite can achieve impressive transaction throughput despite its limitations, such as single-writer architecture. It contrasts SQLite's performance with traditional network databases, demonstrating that eliminating network latency allows for significantly higher transactions per second. The author also discusses batching and the use of SAVEPOINTs for transaction management.

A comparison of various PostgreSQL versions reveals transaction performance, latency, and transactions per second (TPS) metrics. The data highlights that PostgreSQL version 18 achieves the highest transaction count and TPS, while version 17 shows the lowest performance in these areas. Overall, the newer versions generally perform better in terms of latency and transaction efficiency.
