🚀Tailscale Boosts TCP Throughput to 10Gb/s
Tailscale's speed boost is a game changer for devs
TL;DR
Tailscale has improved its TCP throughput to 10Gb/s, making it faster and more efficient for performance-sensitive workloads. This upgrade, set for the second half of 2026, will significantly benefit teams using Tailscale for app connectors and subnet routers.
Tailscale has announced a major upgrade to its product, boosting TCP throughput to 10Gb/s on Linux devices. This improvement is a result of enhancements to Wireguard-go and the implementation of multi-queue technology, which allows for higher aggregate capacity and lower delay. Developers using Tailscale for performance-sensitive workloads will see a noticeable increase in speed and efficiency. The technology will be available in the second half of 2026, with a focus on reducing memory footprint and improving packet handling.
Key Points
Tailscale has improved TCP throughput to 10Gb/s on Linux devices, surpassing 10Gb/s on bare metal.
Multi-queue technology is being implemented to improve throughput by spreading work across CPU cores.
Tailscale has reduced memory footprint by leaving small packets where they landed, leading to a 5% speed-up.
Netmap caching will allow Tailscale clients to start more quickly when the control plane is not reachable.
The multi-queue system allows for higher aggregate capacity and lower delay between receiving and forwarding packets.
Why It Matters
If you're using Tailscale for app connectors or subnet routers, this upgrade is a big deal. The 10Gb/s throughput and multi-queue technology will significantly boost performance, making it ideal for teams with high network demands. The reduction in memory footprint and improved packet handling will also enhance overall efficiency.
