35% Faster Than The Filesystem
1. Summary SQLite reads and writes small blobs (for example, thumbnail images) 35% faster¹ than the same blobs can be read from or written to individual files on disk using fread() or fwrite(). 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
GitHub - flyerhzm/bullet: help to kill N+1 queries and unused eager loading
The Bullet gem is designed to help you increase your application's performance by reducing the number of queries it makes. It will watch your queries while you develop your application and notify you when you should add eager loading (N+1 queries), when you're using eager loading that isn't necessary and when you should use counter cache. Best practice is to use Bullet in development mode or custo
