Update 25/8: I suck at math - I originally posted that pages loaded 74% faster. They actually load 3.9x faster - and the time to load is reduced by 74%. I've edited the below post to reflect this.

2 months ago I wrote about what I accomplished in an hour with Safari Content Blocker. What started off as a one page experiment has since evolved into a full product I've worked non-stop on over the past 60 days. I thought it would be a good idea to revisit my original post with Crystal, to show how different the mobile web will be with content blockers.

10 Websites

For this experiment, I have picked 10 pages from different news websites - Some I use regularly, some I don't. The metrics I'm monitoring is page size (in MB) and load time (in Seconds). 10 pages is far from a good sample size for the web, I know, but the web is a big place, and my time to benchmark is limited.

Websites tested: New York Times, Business Insider, Macworld, Wired, The Verge, PC Gamer, iMore, Kotaku, Huffington Post, Vice.

Method: All sites tested on an iPhone 6+, connected to wifi (154Mb Fiber). All metrics are taken from Safari Web Inspector after doing an Ignored Cache Reload (CMD+Shift+R).

Results

On average, pages loaded 3.9x faster with Crystal and used 53% less bandwidth. Just by having Crystal installed, I saved a total of 70 seconds and 35MB of data on these 10 pages.
