Title: Performance concerns Last modified: June 9, 2020 --- # Performance concerns * Resolved [marvec](https://wordpress.org/support/users/marvec/) * (@marvec) * [6 years ago](https://wordpress.org/support/topic/performance-concerns-3/) * Hello, I have some performance concerns with this plugin. Can you tell me if I do anything wrong, or if there is an option to optimize its usage? My Google Page speed index drops from 86 to 63 just by enabling the plugin. * Overall, I love the plugin. It has all the configuration tweaks I need, it has beautiful popups etc. Just the performance… * 1) partial incompatibility with Total Cache plugin – I need to set JS loading to default synchronous otherwise Hustle fails on page load because it does not have access to jQuery. I have the rules to skip optimizing jQuery JS etc but it still does not help. * 2) jQuery is nowadays a bit dated, Hustle is the only thing on our web that needs it. Is there any plan to rewrite to pure JS? That way I could save a lot of JS. * 3) Hustle loads a ton of CSS and fonts that I do not need. Is there a way to switch that off? * Ideally, I would get a super minified build of Hustle with everything in a single JS and CSS with only things that I need. Is there such an option? * Thank you very much!

The code supposes synchronous loading of jQuery before the plugin. Plus it loads a ton of font CSS (unable to switch them off). With asynchronous JS loading, it does not work: * ``` hustle-ui.min.js?ver=4.2.0:6 Uncaught ReferenceError: jQuery is not defined at hustle-ui.min.js?ver=4.2.0:6 (anonymous) @ hustle-ui.min.js?ver=4.2.0:6 front.min.js?ver=4.2.0:1 Uncaught TypeError: Cannot read property 'extend' of undefined at front.min.js?ver=4.2.0:1 at front.min.js?ver=4.2.0:1 at front.min.js?ver=4.2.0:1 ``` * I really cannot sacrifice our page speed so terribly and harm our SEO. It is such a pity. Such a great plugin and fails on such a silly thing. * Plugin Support [Imran – WPMU DEV Support](https://wordpress.org/support/users/wpmudev-support9/) * (@wpmudev-support9) * [5 years, 12 months ago](https://wordpress.org/support/topic/performance-concerns-3/#post-12968318) * Hello [@marvec](https://wordpress.org/support/users/marvec/) * I trust you’re doing well! * > 1) partial incompatibility with Total Cache plugin * I’ve tested the Total Cache plugin and set the JS to sync and Hustle was working well.

This terribly affects performance. * I managed to fine tune the cache manually so that it loads in async/defer mode. * Would you be interested in a blog post on that topic? I also managed to skip font loading through my theme settings. The performance is now excellent. * It took me 4 hours to just tweak that out, so I think sharing that with your customers/users could be useful to them. * Regards, Martin * Plugin Support [Imran – WPMU DEV Support](https://wordpress.org/support/users/wpmudev-support9/) * (@wpmudev-support9) * [5 years, 12 months ago](https://wordpress.org/support/topic/performance-concerns-3/#post-12979076) * Hello [@marvec](https://wordpress.org/support/users/marvec/) * I hope you’re doing well! * Glad to know that you’ve found a solution. * Please feel free to contact us directly to [contact@wpmudev.org](https://wordpress.org/support/topic/performance-concerns-3/contact@wpmudev.org?output_format=md) for any suggestions. * I’ve marked this ticket as resolved.
