Profiling Python with eBPF: A New Frontier in Performance Analysis Profiling Python applications can be challenging, especially in scenarios involving high-performance requirements or complex workloads. Existing tools often require code instrumentation, making them impractical for certain use cases. Enter eBPF (Extended Berkeley Packet Filter)—a versatile Linux technology—and the open-source project Parca, which together are reshaping how Python profiling works. I’ll cover how eBPF enables continuous profiling, the challenges of stack unwinding in Python, and what modern profiling tools can do with all of this. ...
