Zig
The reason why we can often get away with using languages like Python or JavaScript to drive resource-intensive computations, is because under the hood somebody took years to perfect a C implementation of a key procedure and shared it with the world under a permissive license. - Maintain it With Zig / HN / Home

Zig Interop Overhead Table with Metrics
These are rough per-function call latencies on modern desktop CPUs. Actual values vary based on OS, CPU, type conversion, and data size.
Language | Interop Method | Typical Workflow | Overhead Level | Approx. Call Latency* |
---|---|---|---|---|
Java | JNI | Zig shared lib loaded via System.loadLibrary() |
Low | ~50–200 ns per native call |
JNA/JNR | Reflection-based FFI | Medium | ~1–5 µs per call | |
IPC (sockets, REST) | Zig as separate process | High | ~100 µs – 1 ms per request | |
C++ | C ABI wrappers | extern "C" |
Low | ~5–50 ns per call |
Direct C++ interop | @cImport + C++ |
Medium | ~50–200 ns (depends on ABI, exceptions) | |
Ruby | C extension | Zig lib loaded as native Ruby extension | Low | ~50–200 ns per call |
Ruby FFI (ffi gem) |
Zig C ABI lib via FFI | Medium | ~1–5 µs per call | |
Python | CPython C API | Zig compiled as Python module | Low | ~50–200 ns per call |
ctypes /cffi |
Zig C ABI lib loaded in Python | Medium | ~1–10 µs per call | |
General | IPC | Sockets/pipes/gRPC | High | ~100 µs – 1+ ms per round-trip |
