What is Nusku profiler?

Nusku's a Rust-built, eBPF-powered tool for instant CPU profiling on Linux — attach to PIDs, see hot functions live in terminal, no setup hassle.

Why is performance debugging on Linux so hard?

Tools like perf and bpftrace are powerful but expert-only: root reqs, complex setup, no intuitive live views like Visual Studio offers.

Grab from GitHub (https://github.com/aliamerj/nusku), build with Cargo, run `nusku --pid ` on a hot process. Works on modern kernels.
