konachan_dl

konachan_dl is a script used to download images from konachan quickly.

It downloads images directly onto your drive where ever you want and does so in parallel to achieve faster download speeds, all in your terminal! We also compare performance to the a naive approach to downloading images from the site.

Analysis

In this repo, a simple script is provided that demonstrates the naive 1 by 1 approach to scraping konachan for images. We compare the scripts with batch downloads of 5 and 20 images.

1 by 1 on 5 images

konachan_dl on 5 images

This may seem unimpressive but this difference in speed is only magnified with larger downloads as demonstrated with 20 images.

1 by 1 on 20 images

The numbers speak for themselves. Here are two beautiful images the scraper got in these performance runs
