How Do I Profile eBPF Code?
If we are running any eBPF workload or writing eBPF code, we want to measure its performance impact, and in this post we will demonstrate an example of how to do it.
In this example, our goal is to measure the performance of file open operations, one of the most critical functions in the OS. Our code used file open hooks in eBPF, we wanted to measure the performance overhead introduced by adding this hook.

Summary
Learn how to assess the performance impact of eBPF code by measuring the overhead of file open operations. This practical example highlights the use of eBPF hooks to gain insights into critical OS functions.
