perf Insights | Sumble

What is perf?

Perf is a performance analyzing tool in Linux. It's built into the Linux kernel and provides a powerful way to profile the performance of applications and the kernel itself. It is commonly used to identify performance bottlenecks, analyze CPU usage, memory access patterns, and other performance-related metrics. Perf allows you to sample events, trace function calls, and analyze performance data with various commands and options.
