Sentry engineers uncovered critical performance bottlenecks in their mobile app analysis tools, revealing how O(n²) algorithms slipped past testing only to cause major slowdowns in production. Their investigation exposed quadratic time complexity pitfalls in both Android deobfuscation and iOS binary parsing workflows.

A benchmark reveals how Clang's jump table optimization for UTF-8 sequence length calculations caused a 4x performance drop compared to branch-based approaches. The surprising findings challenge assumptions about lookup tables and highlight the critical interplay between CPU branch prediction and memory access patterns in performance-critical code.
