Does VPN Accelerator really improve VPN speeds by over 400%?
Yes, especially when connecting to VPN servers over large distances or when using a VPN on networks that have packet loss.
VPN Accelerator is built into all Proton VPN apps and ensures no matter which VPN server you connect to or where you are, you will automatically get the fastest speeds possible. You can expect to see speeds that are 400% faster, particularly over less reliable internet connections.
Proton VPN has re-engineered OpenVPN to properly distribute the CPU load between multiple processes, greatly reducing the possibility of a single thread becoming overloaded. We apply similar techniques for all VPN protocols that we support.
VPN Accelerator splits the path between the VPN server and the destination into shorter paths, resulting in higher combined performance over the entire path. It also uses an advanced network TCP flow control algorithm called BBR(new window) to reduce latency and bypass congestion on the internet. Find out more about how VPN Accelerator works.
We use several advanced techniques to increase the efficiency of packet delivery on our networks. These include redesigning the VPN protocols themselves to reduce inefficiencies in their code, modifying the Linux stack on our servers to shorten the normal packet processing path, and using bare-metal servers.
Proton VPN is private by default. We do not require any personally identifiable information at sign up and we implement a strict no-logs policy, meaning we have no data to share. You are able to choose who you share your data with and who you keep it private from.
All Proton VPN apps are completely open source. This means anyone can examine our apps’ code to ensure they are secure and can be trusted with your privacy. We also submit all our apps to audits by independent security experts and publish the final reports online.
Proton VPN was created by the team behind Proton Mail, the world’s largest encrypted email service, and exists only to serve our community. That is why we have donated over half a million dollars to causes that advance freedom on the internet.

Yes, especially when connecting to VPN servers over large distances or when using a VPN on networks that have packet loss.
VPN Accelerator is enabled by default because it can dramatically improve speed performance under certain conditions, with no real downsides. However, the feature can be disabled and enabled in your app’s Settings. See How to use VPN Accelerator for more details.
Yes. Our unique technology can greatly improve VPN speeds, whether you use OpenVPN TCP, OpenVPN UDP, WireGuard, or IKEv2.
No, you will still achieve the best VPN speeds if you connect to a VPN server that is located as close to you as possible. However, if you do connect to a more distant VPN server, or if you are accessing content (i.e., a website) hosted on a server geographically distant from you, VPN Accelerator will dramatically improve your internet speeds.
