hotpath-rs

hotpath-rs is an easy-to-configure Rust performance profiling toolkit that shows exactly where your code spends time, burns CPU, and allocates memory. It helps you distinguish between functions that are slow because they wait on I/O and those that are CPU-intensive. Instrument functions, channels, futures, streams, and SQL queries to find bottlenecks and focus optimizations where they matter most. Get actionable insights into time, memory, and async data flow with minimal setup. You can use it to produce one-off performance (timing, memory or CPU) reports, monitor throughput, performance and max queue depth of instrumented channels, analyze SQL calls performance, or use the live TUI dashboard to monitor real-time performance and async data flow metrics with debug info.
