Nextcloud Hub 26 Winter performance update. 📈 Speed and innovation with the new ADA engine

From small teams to deployments with tens of millions of users:

Organizations worldwide use Nextcloud to build their own private digital workspace, combining different apps and integrations in a fully integrated yet flexible platform.

But how do you keep performance high while the platform is growing? With Nextcloud Hub 26 Winter, we deliver on speed and innovation thanks to:

⚡ The ADA Engine (Accelerated Direct Access): Enjoy super-fast navigation thanks to the significant rewrite of Nextcloud’s database and file access architecture, including:

1. Split tables & sharding
2. Authoritative mount cache & lean data access
3. Direct download of files & previews for S3

🔥 High-performance backends (Rust & Go) for Nextcloud Files and Talk. Make the most of your digital workspace with:

• Direct push notifications to clients
• Reduced sync overhead
• Up to 80% lower server load

🤖 A supercharged Nextcloud Assistant: Access a privacy-first AI-solution that delivers speed and efficiency with:

• Up to 10x faster local AI tasks
• 8x faster local translation
• Improved mobile background performance

These and other updates are the result of customers, partners, and the global Nextcloud community working closely together, building performance improvements that benefit everyone.

For example, in collaboration with partners like Deutsche Telekom (MagentaCLOUD), we managed to deliver:

• Up to 6x faster response times
• 10MB download reduced from 2.5s to 0.4s
• 20–30% database load reduction in heavy clusters

This is what open collaboration at scale looks like: Real-world impact built with and for others.

And, of course, this is just the beginning, as the ADA engine lays the foundation for even greater scalability in the future.
