Page Caching

Hummingbird stores static HTML copies of your pages and posts to decrease page load time.

Page Types

Select which page types you wish to cache. Select which page types you wish to cache.

By default, Hummingbird waits until someone visits your page before generating a cached version. Enable this feature to automatically create cached versions of your homepage or any page or post.

Enable this feature to automatically clear cache at regular intervals only if you are required to do so. Frequent cache clearing can create significant server issues.

Browser Caching

Store temporary data on your visitors’ devices so that they don’t have to download assets twice if they don’t have to. This results in a much faster second time round page load speed.

Gravatar Caching

Gravatar Caching stores local copies of avatars used in comments and in your theme. You can control how often you want the cache purged depending on how your website is set up.

RSS Caching

By default, WordPress will cache your RSS feeds to reduce the load on your server – which is a great feature. Hummingbird gives you control over the expiry time, or you can disable it all together.


Redis is an open source tool for storing data in memory which is used as a database, cache and message broker. It supports many data structures such as strings, hashes and lists and can be easily enabled.

GZIP compression

Gzip compresses your web pages and style sheets before sending them over to the browser. This drastically reduces transfer time since the files are much smaller.

  • HTML
  • JavaScript
  • CSS

Asset Optimization

Optimizing your assets will compress and organize them in a way that improves page load times. You can choose to use our automated options, or manually configure each file yourself.

Asset Optimization hummingbird pro

  • Automatic, Manual
  • Speedy option can be selected under Automatic.
  • Automatically optimize and compress all files.
  • CSS above the fold – Drastically reduce your page load time by moving all of your stylesheets to the footer to force them to load after your content.

This will result in the content loading quickly, with the styling followed shortly after.

  1. Add critical layout and styling CSS here. We will insert into <style> tags in your <head> section of each page.
  2. Next, switch to the advanced area of asset optimization and move all of your CSS files to the footer area.

Advanced Tools

URL Query Strings

Some proxy caching servers and even some CDNs cannot cache static assets with query strings, resulting in a large missed opportunity for increased speeds.

WooCommerce Cart Fragments

WooCommerce uses ajax calls to update cart totals without refreshing the page. These ajax calls run on every page and can drastically increase page load times. We recommend disabling cart fragments on all non-WooCommerce pages.


WordPress adds Javascript and CSS files to convert common symbols like “:)” to visual emojis. If you don’t need emojis this will remove two unnecessary assets.

Prefetch DNS Requests

Speeds up web pages by pre-resolving DNS. In essence it tells a browser it should resolve the DNS of a specific domain prior to it being explicitly called – very useful if you use third party services.

Database cleanup

Cleanup your database of unnecessary data you probably don’t need that’s slowing down your server. You can schedule daily, weekly or monthly automatic cleanups.

Lazy Load

Lazy loading delays loading specific content to speed up the overall pagespeed. In particular, sites with lots of comments, iframes and images can slow down over time.
