How do you guys benchmark C programs in the real world?

I’ve been playing around with benchmarking lately, just using simple stuff like clock() or gettimeofday(), but I’m curious how it’s actually done in professional C development.

What kind of tools or workflows do people use to measure performance properly?

• Are there specific benchmarking frameworks for C?
• What do you use to profile CPU usage, memory, or cache performance?
• Do teams usually integrate benchmarks into CI/CD pipelines somehow?
• And how do you make sure your results are fair and consistent between runs?

Basically, I’m trying to learn what the “grown-up” version of benchmarking looks like in the C world.

Would love to hear what you all use and how you approach it and how it differentiates between different types of programs!
