Does Jetpack Photon slows down the site?


#1

Hey,

I’m using Jetpack Photon since the beginning.

Can someone share their experience or benchmark to prove Jetpack improves site speed or slows it down?

JetPack facts

Cons

  • Increases DNS request by serving images with multi-domains. No more fair approach in my opinion. Gone those days of doing cdn.example.com, css.example.com, js.example.com, extra.example.com to increase parrallel downloading. We are on HTTP/2, we need to forget old theory.
  • High compression for images

Pro

  • Reduces image size up to 50-60% due to WebP.

That makes me love Photon :stuck_out_tongue: Any alternative that would compress images when uploading?


#4

If you want exactly-similar-feature to serve WebP on the fly. It would be bit costly. $20/month. Cloudflare PRO Plan.

Alternatively, I cannot recommend any plugin. Very bad experience.

What if I go with KeyCDN/Stackpath on sub-domain and Jetpack photon together. Is this going to work?

Yes, JetPack can work with it.

Currently, your image path is like this

https://i1.wp.com/www.xyz.com/wp-content/uploads/2018/02/Microsoft-Surface-Book-2.jpg?resize=324%2C235&ssl=1

Later it wil be

https://i1.wp.com/mayank.xyz-cdn.com/wp-content/uploads/2018/02/Microsoft-Surface-Book-2.jpg?resize=324%2C235&ssl=1

Or much cleaner… (if you use custom hostname at CDN)
https://i1.wp.com/cdn.xyz.com/wp-content/uploads/2018/02/Microsoft-Surface-Book-2.jpg?resize=324%2C235&ssl=1

You can use online compression tools like optimizilla.com which I am using and compress the images before uploading.
Reduce the workload to the WordPress as much as possible to improve the performance of the blog.
