Moving beyond fork() + exec()

Linux kernel developer Li Chen has proposed adding "spawn templates" to optimize the inefficient fork() and exec() pattern, which wastes resources by copying an entire process only to discard it when exec() replaces it with a new program. The proposal, while not accepted in its current form, introduces a new approach for applications that repeatedly launch the same executable by caching setup information in a template, reducing overhead by approximately 2% per invocation. Though modest, this optimization points toward potential future improvements to Linux's core process-creation mechanisms.
