[Smush Pro] [Smush Pro] Webp CDN – Slows down site to > 120s

I've noticed that my site slowed down to above 120s for the past couple of days when I had Smush CDN turn on (for webp images) on both front-end and in wp-admin.

Turning Smush CDN off on my back-end made the speed normal again.

Any idea how do I solve this while allowing the site to serve webp images to users who have compatible browsers?

    Hello Daniel,

    how are you doing today?

    I tried to duplicate the issue by activating Smush Pro CDN and WebP conversion on my test site. I didn’t find any slow load times on my test site.

    This is a strange issue and it might be because of some plugin conflict. To further investigate this issue I would request you to grant support staff access so I can take a closer look. You can grant access from WPMU DEV > Support > Support Access > Grant Access, or check this manual: https://premium.wpmudev.org/docs/getting-started/getting-support/#chapter-5

    To investigate the issue I have to activate the Smush Pro CDN again which might slow the site speed. If this is a live website with traffic, I’d rather advise to create a staging environment, meaning a complete and exact copy of this installation into another location/folder in the same server, using a separate database, and perform the test in there instead without worrying about the live site.

    Reference: https://premium.wpmudev.org/docs/getting-started/getting-support/#chapter-2

    Please let us know when you are done granting support access.

    Kind regards,

    Neel Gajjar
