Tags: tracing profiling developer-tools c++ rust performance

Install: brew install uftrace

About:
uftrace is a performance analysis tool that traces function calls within C, C++, and Rust applications. It builds a detailed execution graph, visualizing the relationships and timing between functions. This allows developers to pinpoint performance bottlenecks and understand complex code flow without manual instrumentation.

Key Features:

Visualizes function call graphs and timing
Supports C, C++, Rust, and Go
Provides replay and script-based analysis
Low overhead tracing with kernel integration

Use Cases:

Identifying performance bottlenecks in compiled applications
Understanding legacy codebases and execution flow
Analyzing function relationships in complex systems

Alternatives:

gprof – gprof is a classic profiler, but uftrace provides a more detailed dynamic call graph visualization with less setup.
perf – perf is a powerful Linux profiler focused on system-wide events, whereas uftrace specializes in granular function-level tracing.
