Title: Understanding Defer Options Last modified: October 15, 2020 --- # Understanding Defer Options * Resolved [jamesprw](https://wordpress.org/support/users/jamesprw/) * (@jamesprw) * [5 years, 9 months ago](https://wordpress.org/support/topic/understanding-defer-options/) * On the one hand Hummingbird tells me I can save load size by deferring files such as these: * [https://www.asindera.com/wp-content/cache/min/1/wp-content/uploads/hummingbird-assets/d3316110142acd0d813f489e57bc92f4-4300e6f2b02c250096335876b19e3493.css](https://www.asindera.com/wp-content/cache/min/1/wp-content/uploads/hummingbird-assets/d3316110142acd0d813f489e57bc92f4-4300e6f2b02c250096335876b19e3493.css) * [https://www.asindera.com/wp-content/cache/min/1/wp-content/uploads/hummingbird-assets/0141b788cc92f4a6a8158c961f23580a-cd001501708e0b6546f68c70e6d29256.css](https://www.asindera.com/wp-content/cache/min/1/wp-content/uploads/hummingbird-assets/0141b788cc92f4a6a8158c961f23580a-cd001501708e0b6546f68c70e6d29256.css) * (there are many more) * I understand their purpose, but they don’t show on the list of css assets so I can’t defer them to the footer.

If so, kindly disable any other optmization plugin, we don’t suggest using two optmization plugins as it can cause more issues than benefits. * To understand more about the Assets Optimization you can check those links: * [https://premium.wpmudev.org/docs/wpmu-dev-plugins/hummingbird/#asset-optimization](https://premium.wpmudev.org/docs/wpmu-dev-plugins/hummingbird/#asset-optimization) * Let us know if you have any further question on this.

See this snippet from Google Page Speed insights. I understand what Hummingbird is trying to do but why can’t these be deferred?

Overall however both GT Metrix and Google Page Speed insights say things are worse. It appears that my host response and other outside sources such as Google Analytics, Social Media Attachments and so forth are the main source of the pain – a bad internet day it appears. I’ll monitor over a few days and see how things go. * Plugin Support [Dimitris – WPMU DEV Support](https://wordpress.org/support/users/wpmudev-support6/) * (@wpmudev-support6) * [5 years, 8 months ago](https://wordpress.org/support/topic/understanding-defer-options/#post-13548906) * Hello [@jamesprw](https://wordpress.org/support/users/jamesprw/) * > if Hummingbird could do some of that – specifically NOT caching cart, checkout, > user account and other such pages. * All WooCommerce dynamic pages like carts and checkouts are excluded by default. There is also an additional option to serve cached copies to logged-in users as well. * > I understand what Hummingbird is trying to do but why can’t these be deferred? * Not sure what you mean by that… have you enabled the Advanced Mode in Asset Optimization and already selected the corresponding assets to be deferred or pushed to the footer? Please advise! Ref: [https://premium.wpmudev.org/docs/wpmu-dev-plugins/hummingbird/#assets](https://premium.wpmudev.org/docs/wpmu-dev-plugins/hummingbird/#assets) * Please keep in mind that you should avoid having similar functionalities coming from different plugins. This is a general notice, not only specific to performance plugins. Also, when you setup Asset Optimization it’s advised to deactivate all caches first and enabled them back (along with other services like CDN) after the background processes are finished. * Warm regards, Dimitris * Thread Starter [jamesprw](https://wordpress.org/support/users/jamesprw/) * (@jamesprw) * [5 years, 8 months ago](https://wordpress.org/support/topic/understanding-defer-options/#post-13549631) * Thanks for the suggestions and help.
