Webp significantly slows down the website

[Leftfield]

ProcessWire 3.0.165. PHP 7.2, 7.3 and 7.4

Tried webp like this but it slows down the pages for about 10 seconds and more. Tried cache, same result.

<?= $page->images->eq(0)->size(500,300)->webp->url;

Is there anything else that may be the cause for the slow down?

Only have 3.0.179 for tests on hand but just used exactly your code and only the initial load takes a bit longer as the webp needs to be created. Even older version (before 3.0.165) do very well with webp.

Are there any errors or warnings in the logs? Anything else that shouldn't be? Any image or file modules in place?

@wbmnfktryou are right. I totally forgot autosmush module. When turned off and webp enabled via hook it flies.

Thanks mate!
