Hi,
We have the pagespeed module up and running, I can see it's hashing images.
I recently added the following filters:
ModPagespeedEnableFilters prioritize_critical_css
ModPagespeedEnableFilters sprite_images
ModPagespeedEnableFilters recompress_png
ModPagespeedEnableFilters convert_png_to_jpeg,convert_jpeg_to_webp
ModPagespeedEnableFilters collapse_whitespace,remove_comments
But its made no difference to the score in PageSpeed Insights. Infact, even if I disable the module entirely there is little difference.
I can see in Chrome in the response headers that pagespeed it running too.
The server is running Centos 6.5, what else do I need to check?
Many thanks
Dave
