Peergos, the open source peer-to-peer encrypted filesystem, has reached version 1.24 with performance gains across the board. According to the changelog, the improvements are substantial.

Much faster uploads

The most obvious win shows up when resuming interrupted uploads. For large files, the mechanism that finds the resume point switched from linear scanning to an eight-way branching search. The team reports this as roughly 5,000 times faster. For large folders, the speedup lands around 1,000 times. Starting a fresh upload is also quicker than before.

Deleting large folders received similar attention: by removing some sequential operations and adding a new batch removal operation to the internal data structure, deletion times drop to about a tenth of what they were.

The team also reports hash calculation in the browser is now 8 times faster on machines with 8 cores.

UI and self-hosting improvements

You can now configure the server URL directly from the desktop and Android app interfaces, without manually editing configuration files. This matters especially if you’re pointing to your own instance and want to skip extra setup steps.

The apps also now detect your system’s dark mode preference automatically.

Flatpak users on Linux will need to remove and re-add existing syncs: a bug that’s now fixed was preventing local paths from persisting after updates.

Note for server operators

If you run your own Peergos instance, you’ll need to upgrade to Java 25, which this version requires for virtual thread support.

The recommended installation method on Linux remains Flatpak, available at flatpak.peergos.org.
