Erlang Profiling Techniques
Utilize Erlang's built-in profiling tools to identify performance bottlenecks and optimize your application code.
Why Profile Erlang Code?
Ever wonder why your Erlang application feels a bit sluggish? That's where profiling comes in!
Profiling is like giving your code an X-ray. It helps you:
- Spot performance bottlenecks.
- Understand how functions spend their time.
- Optimize resource usage (CPU, memory).
In Erlang, profiling is crucial for building efficient, high-performance systems.
Meet `fprof`: CPU & Memory
One of Erlang's most powerful built-in profiling tools is fprof. It's designed to give you detailed insights into how your program uses system resources.
fprof can profile:
- CPU usage: Which functions are consuming the most processing time?
- Memory usage: How much memory each function allocates.
It's great for deep dives into specific parts of your code.
