- lucb1e 8y agoAll I noticed is that my browser scrolled less smoothly when an image was in full view. Didn't try with the jpegs but it didn't seem particularly efficient. You could be right though, this is a subjective n=1 kind of remark.
- mistercow 8y agoI posted this elsewhere in the thread, but JPEG seems to be significantly easier to decompress than PNG. Probably mostly due to hardware being optimized for it, but it might also have to do with the way the encoding works. Decompressing JPEGs mostly relies on doing some relatively fixed operations on localized 8x8 tiles, while PNG uses DEFLATE with a window size of up to 32KB.
