Drupal 7 et PageSpeed

13

Le module Apache PageSpeed fournit diverses optimisations pour HTML, JavaScript et autres, ce qui est génial.

Cependant, certaines de ses fonctionnalités sont redondantes avec les propres méthodes d'agrégation et d'optimisation de Drupal. Quelqu'un a-t-il donc testé quels filtres seraient utiles pour un site Web typique de Drupal 7 et lesquels seraient inutiles étant donné que Drupal le fournit déjà?

De plus, est-il plus intéressant de laisser PageSpeed ​​ou Drupal gérer l'agrégation JS / CSS?

Ceci est la section PageSpeed ​​de mon .htaccess:

<IfModule pagespeed_module>
    ModPagespeed on
    ModPagespeedEnableFilters extend_cache
    ModPagespeedEnableFilters collapse_whitespace
    ModPagespeedEnableFilters combine_css
    ModPagespeedEnableFilters move_css_to_head
    ModPagespeedEnableFilters remove_comments
    ModPagespeedEnableFilters inline_css
    ModPagespeedEnableFilters rewrite_javascript
    ModPagespeedEnableFilters insert_img_dimensions
    ModPagespeedEnableFilters rewrite_images
    ModPagespeedEnableFilters rewrite_css
</IfModule>

Bien qu'il y ait un petit chevauchement avec la compression js et css, je ne vois aucun résultat négatif. J'ai configuré Drupal 7 pour agréger et compresser CSS et JS.

Le site n'est cependant pas particulièrement fréquenté.

Vous pouvez également charger les filtres sur une seule ligne, mais je préfère la lisibilité de le faire de cette façon.

Conformément à code.google.com/speed/page-speed/docs/…, vous devez utiliser maintenant insert_image_dimensions, car insert_img_dimensions est déconseillé. Aussi, si je comprends bien, rewrite_images est un sur-ensemble, qui comprend insert_img_dimensions
