Why Bullet Gem? For this Rails optimization, we'll focus on optimizing repeated SQL calls to retrieve objects associated with many relationships: N+1 queries problem. The solution to such an issue is an eager loading association. Unoptimized N+1 affected code takes a significantly longer time as N times additional SQL calls are needed.
