Slowdowns when spawning many child processes (child_process.spawn)

My application needs to spawn multiple processes (e.g. shell commands) concurrently, but performance degrades dramatically with many processes. Why is spawn() slow under heavy usage?

Repeated use of child_process.spawn can be inefficient, especially on platforms where process creation is costly. This can lead to system slowdowns if many processes are spawned concurrently (turn0reddit22turn0reddit24. Better Approaches: • Use Worker Threads for CPU-bound tasks. • Maintain a process pool instead of spawning new processes per task. • Use async queues to throttle concurrent process execution. • Profile spawn usage and reuse long-lived processes where possible. These techniques improve throughput and reduce overhead in concurrent task scenarios.turn0reddit22turn0reddit24
