With SQLite by default nobody else can even read the database while it's being written, so your comment would be better directed to a conventional database server.

Note that the default can be changed with a PRAGMA at compile time to Write-Ahead Logging (WAL) which is both faster and allows reading during writes.

In my limited experiments WAL wasn't faster for high-row-speed writes.

When rows/s are maximized SQLite is CPU limited by internal bytecode operations rather than waiting for disk stuff.

Too late to edit: This should have said "at run time", as it's set by making a relatively normal (can't be inside a transaction) SQL query.
If you enable the WAL, reading while writing is possible. IMO it should be the default.
