How fast is SQLite?

Is SQLite fast enough?

SQLite is fast and reliable and it requires no configuration or maintenance. It keeps things simple. SQLite "just works".

Is SQLite faster than SQL?

SQLite is generally a lot faster than SQL Server. However, SQLite only supports a single writer at a time (meaning the execution of an individual transaction). SQLite locks the entire database when it needs a lock (either read or write) and only one writer can hold a write lock at a time.

Is SQLite faster than file?

Reading and writing from an SQLite database is often faster than reading and writing individual files from disk. See 35% Faster Than The Filesystem and Internal Versus External BLOBs. The application only has to load the data it needs, rather than reading the entire file and holding a complete parse in memory.

Why is SQLite so slow?

The SQLite docs explains why this is so slow: Transaction speed is limited by disk drive speed because (by default) SQLite actually waits until the data really is safely stored on the disk surface before the transaction is complete. That way, if you suddenly lose power or if your OS crashes, your data is still safe.
