Ian Carrico and Jason Ormand discuss what the team has done, how it did it, and what it’s still working on. Ian and Jason start with the big items that the team knew it could improve upon—images and fonts. Both are very large parts of Vox sites (in both importance and size): the team needed to get images sent down the pipe as small as possible, implementing WebP where able, and fonts needed to be sent as asynchronously as possible without hurting UX.
