Gzip Compression while usng Amazon CloudFront CDN

  • I enabled CloudFront CDN in W3C.
    I was surprised when my PageSpeed rating dropped from 85 to 34.
    The problem is compression. The content stored on CloudFront is not using compression.
    There is a setting for your CloudFront Distributions (Behavior/Compress Objects Automatically) where you can let AWS to compress content automatically.
    By default it was set to false. I changed it but there is no effect ??
    The second, W3C has note on CDN page If using Amazon Web Services or Self-Hosted CDN types, enable HTTP compression in the “Media & Other Files” section on Browser Cache Settings tab. I checked it and compression is on.

    Do you have an idea why compression is not working? The logic says that it should be compressed twice, by w3c and by AWS.
    Without CDN enabled compression is ok.
    Is there some additional setting needed?

    Thanks
