# CPU Profile

This is a simple package to measure CPU speed by calculating the time it takes to

compute Fibonacci numbers. It is useful in contexts where CPU speed is unknown or can

fluctuate, such as cloud function environments, and can serve as a rough measure of how

long subsequent compute-intensive code will take to run.

## Installation

```sh

pip install cpuprofile

```

## Usage

```python

from cpuprofile import profile_cpu

# Calculate the CPU speed by computing Fibonacci numbers.

elapsed_time = profile_cpu()

# elapsed_time is ~0.18 (seconds) on a 2.5 GHz Intel Core i7 2015 Macbook Pro.

# Or, a number can be specified to calculate the nth Fibonacci (default: 28).

elapsed_time = profile_cpu(15)  # 15th Fibonacci; takes around 0.0006 seconds

elapsed_time = profile_cpu(35)  # 35th Fibonacci; takes about 5 seconds

```

The minimalist approach of recursively calculating Fibonacci numbers as a way to profile

the CPU is inspired by:
