A developer discovered that a Node.js `execFile` operation was significantly slower than a direct socket connection due to the overhead of spawning a separate Rust binary process. However, upon closer inspection and timing the subprocess itself, the developer found that the actual execution time of the binary was minimal. The perceived slowness was attributed to the Rust daemon performing a more extensive operation when called via the CLI compared to the direct socket call, not the act of spawning the process. AI
