Description

child_process takes ~20ms to run a script with execSync. If this can be optimized further, that would be great.

Use case

I have ported some bash scripts to Node.js to make them more easily cross-platform. But sometimes that means using child_process to call out to other programs (e.g. git). These calls can add up and make me think twice about the performance tradeoff.

Benchmark

Here's a benchmark: https://github.com/mehulkar/bench-childprocess

Research direction

Start by running the benchmark linked in the issue and reviewing Node.js child_process usage around execSync. Compare the measured runtime with the reported ~20ms baseline; the work is done only if a concrete optimization is identified and validated by improved benchmark results.
