Have you any advice on compressing assets that are located on Facebook CDN?
I have enabled remote support so that you can have a look if you wish.
For further info please see the results below from Hummingbird
Enable compression for the following resources to reduce their transfer size by 522.1KiB (71% reduction).

Compressing https://static.xx.fbcdn.net/rsrc.php/v3iEpO4/yn/l/en_US/cpVPm_rBILj.js could save 359.1KiB (72% reduction).
