Nextcloud Faster in 2025: How to Supercharge Your Private Cloud

Nextcloud has always been about giving you control over your data. But in 2025, we took a huge leap forward—not just in features, but in speed. From large teams to individual users, we heard your feedback and got to work. The result? A Nextcloud faster than ever before.

In this article, we’ll walk you through what changed, how it helps you, and how to make the most of these upgrades—no complex tech talk, just practical insight.

Why We Needed to Make Nextcloud Faster

Let’s be honest: as more users joined, the demand on servers grew. Uploads lagged. Notifications delayed. Even opening a shared folder could feel slow on larger deployments.

Our goal was simple—make Nextcloud as fast and responsive as top cloud providers, but without compromising privacy or self-hosted control.

Introducing the High-Performance Backend (HPB)

The star of the show is our High-Performance Backend (HPB). Built using Rust, this lightweight but powerful engine is a game-changer.

What Is HPB and Why Does It Matter?

  • It removes the old polling method and replaces it with real-time updates.
  • Notifications, file syncs, and calls now feel instant.
  • Reduces load on both the server and network.

HPB now powers Nextcloud Files, Nextcloud Talk, and more—helping your system run smoother and faster.

Real Speed Gains You’ll Notice

Measurable Improvements

  • Notifications deliver up to 90% quicker.
  • Server CPU usage dropped by 40% on average in large deployments.
  • File syncing now happens in near real-time.

Real-World Use Case

An education provider in Germany running Nextcloud for over 20,000 students saw a 35% drop in server response times and a 50% improvement in video call stability after enabling HPB.

Lighter Apps, Smarter Loads

We didn’t stop at the backend. The front-end got an upgrade too:

App Bundles via Vite

Nextcloud apps now load faster thanks to Vite, a modern JavaScript bundler that speeds up initial page loads and interactions.

Less Memory, More Efficiency

  • Smaller JavaScript files mean less data downloaded per page.
  • Reduced memory use = better performance on low-powered devices.

Nextcloud Talk: Big Improvements for Teams

If you use Nextcloud Talk, you’ll love the speed boost:

  • High-Performance backend for Talk now supports massive calls with 500+ participants.
  • Improved audio/video sync.
  • SIP bridging allows calling external phone numbers from inside Talk.

This makes it ideal for remote teams, schools, and even enterprise webinars.

Database & Caching Upgrades

We reworked how Nextcloud talks to your database.

Read-After-Write Behavior

This new approach allows faster reads immediately after uploads—great for collaborative document editing or chat messages.

Redis, Opcache, and Tuning

Proper use of Redis, PHP Opcache, and smart database indexing now plays a huge role in performance. We offer tools to help configure this automatically.

How You Can Make Your Nextcloud Faster Today

Here’s what you can do right now:

  1. Enable the High-Performance Backend
    If you’re self-hosting, install the HPB service and connect it to your instance using your trusted domain.

  2. Use Redis and Memory Caching
    Update your config.php to include memory cache settings for Redis or APCu.

  3. Upgrade to Nextcloud Hub 9 or Later
    New performance improvements are only available in the latest versions—always keep your system updated.

  4. Optimize Your Hosting Stack

    • Use SSDs over HDDs
    • Use HTTP/2 or HTTP/3
    • Offload static files with a CDN
    • Monitor usage with tools like Netdata or Glances

Designed for Everyone: From Home Users to Enterprises

Whether you’re running Nextcloud on a Raspberry Pi or in a corporate data center, these performance upgrades are designed to scale.

  • Small teams will see quicker syncs and smoother sharing.
  • Enterprises can now support thousands of users with less hardware and better uptime.
  • IT Admins can monitor server health and optimize performance more easily than ever before.

What’s Next in the Performance Pipeline?

We’re not done yet.

  • AI Assistant is getting faster, too—processing requests in real time with local models.
  • Better load balancing across nodes is coming soon.
  • Enhanced caching for federated sharing will reduce sync times for shared files between organizations.

Conclusion

Making Nextcloud faster wasn’t just about shaving seconds off load times—it was about building a better experience for everyone. With the high-performance backend, app bundling, and smarter database logic, we’ve made huge strides in speed and stability.

Want to feel the difference? Update to the latest version, enable HPB, and try it out. Your Nextcloud experience is about to get smoother, faster, and more enjoyable.
