I just took that image (which is 3300 x 2200), resized it to 50% and got 1.05 MiB, instead of 5.85. Threw it through JPEGMini (a paid product, mind you) and got 729 KiB.
Guetzli is nice, but it's slow as balls. JPEGMini is a decent alternative. (I'm a happy customer of JPEGMini, BTW. No other affiliations.)

I'm making something in between [1].
That image is a good example for any perceptual encoder. At 50% size it's 600KB (487KB with current master), and there's still a lot to be unhappy about, e.g. a hidpi image like that can be compressed a lot harder.
Over 6MB of those 10MB is just one bloated photo [1]. It can be compressed down to 1-2MB. Moreover, if it was a proper responsive image, it would not be larger than 100-200 KB for most readers because a good JPEG compressor can pull 2 bits per pixel [2].
Ironically, image optimization apps don't get that much coverage.
