How We Uncovered Hidden Bottlenecks in Rust Services with Profiling

After migrating thousands of Java cores to Rust, the team used jemalloc and pprof profiling to pinpoint why a few services only improved 10%, refactored the OSS client for reuse, and achieved up to 20% CPU reduction and significant memory savings, demonstrating the power of deep performance analysis in production Rust services.
