Question 1

How do I pause and resume timing with plf::nanotimer?

Accepted Answer

Since it lacks a built-in pause function, you must manually sum elapsed times. Start the timer, get elapsed time, do other work, then restart and add new elapsed time to the previous total, as shown in the README example for 'timer pausing'.

Question 2

Is plf::nanotimer accurate for nanosecond measurements?

Accepted Answer

It provides nanosecond measurements via get_elapsed_ns(), but actual accuracy may be limited to microsecond precision on some platforms. For true nanosecond accuracy, hardware-specific timers or more advanced libraries might be necessary.

Question 3

plf::nanotimer vs std::chrono: which is better for C++ timing?

Accepted Answer

plf::nanotimer is simpler with lower overhead, ideal for quick benchmarking. std::chrono is standard, offers more features like type-safe durations, but may have slightly higher overhead. Choose based on simplicity vs. standardization needs.

Question 4

How to use plf::nanotimer in a cross-platform C++ project?

Accepted Answer

Include the header file and use the class as shown in the README. It's designed for cross-platform use with no dependencies, but ensure your compiler supports at least C++03 and test on target platforms for consistency.

Question 5

Can plf::nanotimer be used for real-time system benchmarking?

Accepted Answer

Yes, its minimal overhead makes it suitable for real-time applications. However, verify delay functions and timer accuracy meet specific requirements, as OS scheduling or hardware limitations might affect precision in hard real-time systems.

Question 6

What are the delay functions in plf::nanotimer useful for?

Accepted Answer

The non-member delay functions (e.g., plf::microsecond_delay) allow precise program pauses, useful for testing timing sensitivity or simulating delays in benchmarking scenarios, though accuracy depends on the platform.
