Gonzales is not another clone of WordPress performance plugin. So what’s the difference between this and other optimization tools? It truly gets rid of problem by excluding JS/CSS from HTML code while other speed up plugins mask problem only - they use compression/merging method to minimize website size. In fact such a website still loads useless files which affect website performance. If you conditionally disable plugins you will definitely see difference in document loading time, especially when requests cannot be cached.
Gonzales uses brand new way of WordPress optimization method which other plugins do not use. I don't want you to uninstall other awesome tools like Cache Enabler, W3 Total Cache, WP Super Cache or WP Rocket - Gonzales works with them symbiotically and you don't need to configure anything! Nice way to speed up WordPress, huh?
Well, you should. Even thought timings to all resources are the same you still forces people users to download the same large CSS/JS files. Once you use Gonzales website will be delivered faster to browser even with HTTP2. To verify if you use HTTP1.1 or HTTP2 use HTTP2 tester powered by KeyCDN team.
One of interesting options of plugin is silent mode. Once you complete optimizations you can switch Gonzales to work in background (disable menu and hidden panel). To do it define DISABLE_GONZALES_PANEL in function.php file of your theme. Thanks such a approach you will save preciouse top admin bar space and Kbytes in RAM.
There's long list of actions you must take to achieve great performance results but they need a lot of your attention. I suppose your time is precious and highly limited so here is what I recommend to read once you buy Gonzales: “How to move scripts to bottom with or without W3 Total Cache”. Hey, don't forget about PHP7 which is officially available since December 2015. Thanks new version of PHP7 you can get much better performance and depending on hosting you can enable it by adding one line to .htaccess or switching checkbox in administration section of hosting panel. I recommend Kinsta.
