Lofesa commented on issue #1543: Problem with pagespeed filters URL: https://github.com/apache/incubator-pagespeed-ngx/issues/1543#issuecomment-371473980 Hi again pagespeed need some hits to get optimized resources and these optimized resources had a ttl based on what cache expires they have, when this time come need to re-optimize. This work is done if the resource is public cacheable. For example prioritize_citical_css need 4-5 hits to work and need that beacon be enabled. CoreFilters enable these: add_head combine_css combine_javascript convert_meta_tags extend_cache fallback_rewrite_css_urls flatten_css_imports inline_css inline_import_to_link inline_javascript rewrite_css rewrite_images rewrite_javascript rewrite_style_attributes_with_url have you configured a manager to .pagespeed.xxx optimized resources? I think you need pagespeed CriticalImagesBeaconEnabled true; to some filters to work and to get optimized resources stay more time in the cache you need to enable pagespeed FinderPropertiesCacheExpirationTimeMs TtlInMs; Try to view what is happen using /?PageSpeedFilters=+debug as a url parameter. This inyect debug info in your html code.
