As you can see these are all external resources and that being said, W3 Total Cache or any other plugin for that matter cannot handle those files because they are coming from the external server. In Performance>Browser cache you can set: Set Last- Modified header Set expires header Set cache control header Set entity tag (ETag) Enable HTTP (gzip) compression This will take care of all static files on your server setting the expires header, cache-control, gzip, ETag, etc. As for Minify JS things, can you please be more specific? Thank you! * Thread Starter [sbraunm](https://wordpress.org/support/users/sbraunm/) * (@sbraunm) * [6 years ago](https://wordpress.org/support/topic/leverage-browser-caching-72/#post-12814546) * Hello Marko, and thanks for your continuos support for W3. * You can see the minify list here: * > [View post on imgur.com](https://imgur.com/2pqFDNH) * There is also a small defer parsing list here: * > [View post on imgur.com](https://imgur.com/JM8owwk) * Kindly advice, * thank you * Plugin Contributor [Marko Vasiljevic](https://wordpress.org/support/users/vmarko/) * (@vmarko) * [6 years ago](https://wordpress.org/support/topic/leverage-browser-caching-72/#post-12814792) * Hello [@sbraunm](https://wordpress.org/support/users/sbraunm/) * Again all external resources and cannot be handled by W3 Total Cache. Your test results are great. [https://gtmetrix.com/reports/www.nationalallergyperu.com/gP1tADLE](https://gtmetrix.com/reports/www.nationalallergyperu.com/gP1tADLE) Your website loads under 2s and the overall score is 93 which is great. Those recommendations for minifying suggest reducing the size by 1% which is basically a statistical error and it would not increase the score. You might want to enable the “Disable Emoji” option in Performance>User Experience to remove emojis (unnecessary). To conclude, your website load speed and score are great and the user experience is awesome. Thank you! * Thread Starter [sbraunm](https://wordpress.org/support/users/sbraunm/) * (@sbraunm) * [6 years ago](https://wordpress.org/support/topic/leverage-browser-caching-72/#post-12814908) * 2secs? I see around 6secs everytime and can not reduce it. In any case there nothing else to do at W3 level, right? * Plugin Contributor [Marko Vasiljevic](https://wordpress.org/support/users/vmarko/) * (@vmarko) * [6 years ago](https://wordpress.org/support/topic/leverage-browser-caching-72/#post-12815436) * Hello [@sbraunm](https://wordpress.org/support/users/sbraunm/) Yes as you can see in the test results. No, nothing else can be done.
