One of the greatest perks of my job is that I get to talk to geniuses on a daily basis. I was extremely privileged to be able to chat recently with yet another genius: Joshua Marantz, leader of mod_pagespeed at Google.
We covered a lot of ground, from philosophical to pragmatic topics. You’re going to enjoy this podcast if you’ve ever wondered:
- What the heck is the difference between PageSpeed and mod_pagespeed?
- Where does front-end optimization belong in order to deliver the best possible results: near the edge, near the server, or some point in between?
- Will FEO someday be completely taken care of at the browser and server level?
We also talked quite a bit about images, which has been a recurring theme here lately. While Josh and I agree that what’s unambiguously good for the speed of a page is aggressive lossless image compression, he explains why that feature is not turned on by default in mod_pagespeed (though he says that he always tells people that it’s the first feature they should try to turn on).
Enjoy. And as always, if you have any questions, feedback, or suggestions for future guests or topics, drop me a line at joshua[[at]]webperformancetoday[[dot]]com.
