I think your better off looking at logs, or running a benchmarker/code profiler for the application. If you watching apache processes spin up and down and wondering how long, I would just up the debug log, and what for servers to be spun up and down.

If auditd couldn't do it, though, I'd turn around and look at something like SystemTap, which certainly could, though it would require some elbow grease to write the BPF program to assemble the events and log entries I wanted. (Though to be clear, you could very likely have it give you the entire process lifecycle timing.)
