I draw comics and webcomics. Comics is a passion of mine since I was a kid. It is important that my webcomics loads fast and clear. I am particular on site caching.
Jetpack had an option called “Photon.” Photon accelerated images by using WordPress.com as a Content Delivery Network. Photon did the reverse for my images. My sites loaded very slow. If my site lost its connection to WordPress.com, my images would not load at all. I stopped using the Photon option.
Jetpack merged Photon with a new option called “Site Accelerator.” I was skeptical about activating this option because of my experience. To my surprise, the Site Accelerator did NOT screw up my webcomic; it improved my site’s load speed.
I am happy that Jetpack continues to improve their service. I am also happy that my load speeds improved.
