SQLite vs PostgreSQL

The post compares SQLite and PostgreSQL regarding their performance in various operations such as inserts, updates, deletes, and joins. It highlights the differences in architecture, with PostgreSQL being a traditional client-server database and SQLite functioning as a library integrated into the application. Tests are conducted to measure latency, throughput, CPU usage, and disk write operations, emphasizing how network interactions impact PostgreSQL's performance compared to SQLite's local file interactions.
