Rust: Doubling Throughput with Continuous Profiling and Optimization

“68.37% of CPU [...] with a one-line code change [...] went down to 31.82%”

S2 needed a solution to identify optimization opportunities during load testing and gain deeper insights into system bottlenecks under normal operations. Polar Signals Cloud provided S2 with continuous profiling capabilities, allowing the team to easily analyze performance data rather than relying on ad hoc tools like perf. The flexibility in pricing also played a crucial role in addressing S2's unique challenges, as resource usage was influenced not just by CPU cores but also by code deployment frequency.
