Hummingbird Page Speed Optimization


Hummingbird zips through your site and finds new ways to boost page speed with fine-tuned controls over file compression, minification and full-page, browser and Gravatar caching. Load your pages quicker and score higher on Google PageSpeed Insights with Hummingbird site optimization.

Features Available in Hummingbird Include:

  • Performance Reports – Pro tips for running your site at super speed
  • Minification – Position, minify and combine files for top performance
  • Caching Suite – Load pages faster with full-page, Gravatar and browser cache tools
  • GZIP Compression – Blazing fast HTML, JavaScript, and stylesheet transfer

Scans and Recommendations

Hummingbird will scan your site, find files that are slowing it down and provide tips and fixes for making your site run at top speed.

Hummingbird even has one-click improvements for quickly optimizing performance.

“Hummingbird is so easy to use. I thought it wouldn’t change my speed much because I already made improvements. I ran the scan, it gave me recommendations, I pushed a button to apply them and it made my site even faster!” – Camilo

“Hummingbird took me from 32 to 84 on Google page speed plus made my site 50% faster on GTmetrix!” – Nicolas

“I just built a real bloated sack of crap of a WP site, and after configuring Hummingbird and letting it do its thing, the site is actually fast — much faster than it has any right to be…I’m impressed.” – Cacarr


Did you know that the more files you add to your site’s the header, the slower it will load? With Hummingbird, you can easily customize the load position of your files to increase your page speed.

Quickly reorder, compress and reposition files with Hummingbird’s minification feature. But play carefully – minification is a powerful tool (though if you need it, you can reset any changes you make in one click).

Transfer Data at Top Speed with GZIP

Hummingbird has GZIP powers to make sharing your site more efficient.
Sending zipped files is faster and can save you money on hosting. And don’t worry about setup, send Hummingbird instructions with the click of a button and she’ll handle the rest.

Full-Page, Browser and Gravatar Cache

Make your site load even faster for with Hummingbirds complete set of cache tools that give your visitor’s a fastor browsing experience. Including full-page, broswer and Gravatar caching.

Built-in Cloudflare Integration

Hummingbird can be used to control your Cloudflare browser cache settings as well! Simply add your Cloudflare API details and configure away.

Hummingbird is a one of a kind WordPress performance optimization plugin that can make your site run at superspeed, for free!

However, if you’d like automated scanning, uptime monitoring, enhanced minify compression with up to 2x the regular optimization, CDN hosted minification and Smush Pro image optimization you can always take the next step with a WPMU DEV Membership.

Do I need Hummingbird if I already have WP Rocket or W3 Total Cache?

Yes! Of course our cache suite is more than enough but if you already use WP Rocket or W3 Total Cache the special monitoring tools Hummingbird offers still make it worth it. To ensure compatibility only activate overlapping features in one of the plugins.

Does Hummingbird work with Cloudflare?

Yes! Hummingbird is built to take full advantage of Cloudflare features. Just plug in your API to get started.

Does Hummingbird work with WooCommerce?

Yes! Hummingbird works great with ecommerce plugins like WooCommerce and MarketPress. For best results, when configuring full-page cache, follow the WooCommerce recommended cache settings. Hummingbird will exclude the cart, my account and checkout pages to keep content dynamic.

Somebody help! I turned on Minification and it broke my site!?

Minification is a great way to speed up your site but moving, combining and rearranging files can also mess with styling and break functionality. We recommend making incremental changes and testing your site as you go so you can undo the changes if something breaks. And remember, don’t panic. If something goes wrong you can start over with the click of a button 🙂



Great plugin for those who practice content marketing with SEO techniques, easy to use and quite complete. Like everyone else in this company.

Works great if you use it right

It actually works great. You have to go through each option to make sure its turned on and that the server is showing the correct one for you.lightspeed, apache, ngix etc make sure you select the right one or it wont work.

Otherwise brilliant. Shame you cant connect to keycdn through it.
