Async vs. Sync - Difference in speed

I was bored then I decided to compare synchronous and asynchronous programming using Python and some libraries like asyncio and aiohttp

Deployment

To deploy this project you need Python installed with its package manager pip

Open command line in project folder and run following command:

  pip install -r requirements.txt

Usage/Examples

Sample output for sync_main.py:

  Downloading pic 1
  Downloading pic 2
  ...
  Downloading pic 11
  Downloading pic 12
  Time: 5.90338134765625

Sample output for async_main.py:

  Downloading pic onepunch_man_202_7.jpg
  Downloading pic onepunch_man_202_4.jpg
  ...
  Downloading pic onepunch_man_202_5.jpg
  Downloading pic onepunch_man_202_9.jpg

Difference

Synchronous	Asynchronous
9,71s	2,59s
9,17s	2,54s
9,17s	2,24s
8,25s	2,06s
6,41s	2,3s
6,00s	4,4s
6,12s	2,11s
Avg: 7,83s	Avg: 2,61s

Difference will grow exponentially as amount of data grows
