35% Faster Than The Filesystem 1.

Furthermore, a single SQLite database holding 10-kilobyte blobs uses about 20% less disk space than storing the blobs in individual files. The performance difference arises (we believe) because when working from an SQLite database, the open() and close() system calls are inv...
