How SQLite is fast?

Question

Developers report that SQLite is often faster than a client/server SQL database engine in this scenario. Database requests are serialized by the server, so concurrency is not an issue. Concurrency is also improved by "database sharding": using separate database files for different subdomains.

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 SQLite is faster than MySQL?

SQLite3 is much faster than MySQL database. It's because file database is always faster than unix socket.
