This releases addresses some performance issues and bugs found since the v2.12.0 release.

What's Changed

  • Try to use GRO and GSO by default, when supported, for more efficient sending/receiving (when sup (#29). They can be disabled if needed through new command-line options, but should fail gracefully if the server doesn't support them (albeit at slightly higher CPU usage).
  • Change the default node-to-node QUIC congestion algorithm to cubic instead of bbr, as testing is showing bbr exhibiting some slower and worse performing throughput between data-center connections (and also requires higher CPU). Same PR as above.
  • Increase (via new libquic package) the system maximum allowed socket buffers, and use them for quic connections. Same PR as above.
  • Fix a potential crash at shutdown by dropping pending uWebSockets work after the server thread exits (#27)
  • Reduce database write contention; respect expiries (#30)
  • Treat a BUSY oxend as syncing instead of exiting at startup (#31)
  • Add --db-slow-query-ms to log slow database statements (#26)

Full Changelog: v2.12.0...v2.12.1

Upgrading

As usual, upgrades are available from our APT repository (the old deb.oxen.io address continues to work). Static binaries for other users are available below.

Debian 11 ("bullseye") and Ubuntu 20.04 ("focal") are no longer supported, as they have reached end of life and no longer receive security updates. Packages are now provided for Debian 12+ and Ubuntu 22.04+. Operators still on those distributions should upgrade as soon as possible.
