Yes, especially when you connect to VPN servers over long distances or use a VPN on networks with packet loss.
Fastest possible VPN connection
Boosting speed everywhere
VPN Accelerator is built into all Proton VPN apps. You'll automatically get the fastest speeds possible wherever you are, no matter what VPN server you connect to. You can expect speeds that are up to 400% faster, especially over less reliable internet connections.
Beating CPU limitations
Proton VPN has re-engineered OpenVPN to properly distribute the CPU load between multiple processes. That greatly reduces the possibility of a single thread becoming overloaded. We apply similar techniques for all VPN protocols that we support.
Reducing latency and network congestion
VPN Accelerator splits the path between the VPN server and the destination into shorter paths. That gives a 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.Learn more about how VPN Accelerator works
Improving packet forwarding
We use several advanced techniques to increase the efficiency of packet delivery on our networks. These include redesigning the VPN protocols 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.
