Learn how to effectively profile CPU and memory for C++ applications using tools like perf, VTune, and Instruments to optimize performance.

Profiling with perf

Perf is a powerful Linux tool that helps in profiling various metrics. Here's how you can use it:

sudo perf record -g ./your_application # Record performance data sudo perf report # View performance report

Profiling with VTune

Intel VTune provides detailed insights into CPU performance. To use it, follow these steps:

vtune -collect hotspots -- ./your_application # Collect hotspot data vtune -report summary # Generate a summary report

Profiling with Instruments

Instruments is available on macOS and is ideal for profiling memory usage:

# Open Instruments, select your application and choose "Allocations" for memory profiling.

By utilizing these tools, you can gather critical information about application performance, leading to better optimization and resource management.
