Help us improve Hummingbird by letting our product designers gain insight into what features need improvement. We don’t track any personalized data, it’s all basic stuff.

We developed automatic optimization so you can spend less time on configuration, while still seeing the same positive results that can be achieved through manual optimization.

Migrate your settings

Set comment threshold to lazy load comments.

The browser won’t begin fetching the resources before it needs them, but at least it can handle the connection aspects ahead of time, saving the user from waiting for several roundtrips when your browser is fetching the resources from this origin.

With new optimization you will be able to automatically optimize your CSS and JavaScript files by just enabling the Basic or Speedy optimization option. Check the “How does it work” section, to know what each automated feature does behind the scenes.

Speedy optimization is a higher level of optimization, as it not only compresses your files but it also "auto-combines" smaller files together (*only when two or more files have identical attributes), which helps to reduce the number of requests made when a page is loaded.

Saving settings

OpCache stores script bytecode in memory so PHP scripts don't have to be loaded and parsed with every request. OpCache cache will be cleared when you click “Clear cache” button located in the admin bar.

Some plugins and themes are not able to handle deferred scripts. If the combine and minify all CSS option does not work on your setup, we recommend trying multiple combinations to find the best configuration for your site.
