How many concurrent users SQLite?

Does SQLite allow multiple connections?

SQLite does support multiple concurrent connections, and therefore it can be used with a multi-threaded or multi-process application. The catch is that when SQLite opens a write transaction, it will lock all the tables.

Is SQLite concurrent?

Usually, SQLite allows at most one writer to proceed concurrently. The BEGIN CONCURRENT enhancement allows multiple writers to process write transactions simultanously if the database is in "wal" or "wal2" mode, although the system still serializes COMMIT commands.

How does SQLite handle concurrency?

SQLite has a lock table that helps locking the database as late as possible during a write operation to ensure maximum concurrency. The initial state is UNLOCKED, and in this state, the connection has not accessed the database yet.

How many requests per second can SQLite handle?

Actually, SQLite will easily do 50,000 or more INSERT statements per second on an average desktop computer. But it will only do a few dozen transactions per second. Transaction speed is limited by the rotational speed of your disk drive.
