Slow tiles generation for leaflet js

I am currently trying to use leaflet to display images (jpeg or png) instead of maps, I have followed the instructions on this blog post to create the tiles using gdal2tiles.py here is the code we used 

gdal2tile.py -p raster -z 0-5 -w none "SOURCE_PATH.png" "DESTINATION_FOLDER"

The command produces the necessary tiles for leaflet, but the problem is that it takes around 2 minutes to create tiles for the attached image (size: 777KB, resolution: 2592x1728) and a disastrous number of tiles of around 1600 file.

I am trying to optimize the time and number of files to generate tiles for leaflet and looking for suggestions, please help.

Like the blog post explains, your image's resolution is too low to zoom further than 3 times. So change that to 0-3 and you'll see things speed up considerably.
