How I use a stopwatch with laps for small tests

A chronometer is useful for quick manual timing when a full benchmark is unnecessary.

The Chronometer tool handles the repetitive part so I can focus on checking whether the result makes sense.

The simple idea

A chronometer is useful for quick manual timing when a full benchmark is unnecessary.

I still treat the output as something to review, especially when it affects money, dates, privacy, or production data.

Step 1: Start the timer when the action begins

Step 2: Use laps for repeated steps

Step 3: Stop when the action ends

Step 4: Compare lap times

Step 5: Repeat the measurement if precision matters

Step 6: Avoid using manual timing for very small operations

Step 7: Use a proper benchmark for code performance decisions

My checklist

Before I trust the result, I check:

• Start the timer when the action begins.
• Use laps for repeated steps.
• Stop when the action ends.
• Compare lap times.
• Repeat the measurement if precision matters.
• Avoid using manual timing for very small operations.
• Use a proper benchmark for code performance decisions.

A small tool is most useful when it makes the work visible and easy to verify.
