AI Analysis
●●SolidBig BrainWizardry
Removing branches from Quicksort cuts sort time in half on Apple Silicon.
Strengths
- •Demonstrates tangible 2x speedup by mitigating branch misprediction penalties.
- •Provides clear comparative benchmarks against std::sort and pdqsort.
Weaknesses
- •Optimization is highly specific to sorting; limited broader applicability.
- •Most developers should just use std::sort or pdqsort instead.
