Calculate the total and average execution time of a function. Measure the time taken for a specific number of runs.

Function Execution Time

Purpose

The Function Execution Time calculator is used to measure the time taken for a specific function to execute in your web app. This can help in understanding the performance of the function and optimizing it if needed.

Use Cases

• To measure the time taken for a function to execute.
• To compare the performance of different functions.
• To identify any bottlenecks in the code that may be causing delays.

How to Use

1. Enter the function expression you want to measure in the provided input field.
2. Specify the number of times you want the function to run for a more accurate average execution time.
3. Click on the "Calculate" button to see the results.

Input Values

1. Function Expression: Enter the function expression you want to measure.
2. Number of Runs: Specify the number of times the function should run for accurate measurement. (default unit is 'time')

Output Values

1. Total Execution Time: The total time taken for the function to execute. (unit: seconds)
2. Average Execution Time: The average time taken for each run of the function. (unit: milliseconds)

Any other Instruction

• Make sure to enter a valid function expression to get accurate results.
• Increasing the number of runs can provide a more reliable average execution time.

Steps of Calculation

1. The function will run the specified function expression for the specified number of runs.
2. It will measure the total time taken for all runs and calculate the average execution time per run.

Technical Parameter names

• xpr, number_of_run

Return Values

• Total Execution Time, Average Execution Time

Example Expressions

You can use the following expressions to directly evaluate in a non-interactive manner using eval():

xtime("math.sqrt(16)", 50)
xtime("sum(range(100))", 100)
