For these matters the "perf" utility in the linux-perf package reaches
near-uninstrumented performance:

$ perf record <exe_and_arguments> # Gather results

$ perf report # Inspect results

Depending on the system configuration, running previously a

$ echo 1 | sudo tee /proc/sys/kernel/perf_event_paranoid

might be required.
