AdGuard VPN v2.10 for Android: ultimate speed
We have been working on improving the connection speed of our VPN for some time now, and with AdGuard VPN v2.10 for Android, connecting to different locations has become faster and more reliable, even in regions where VPNs typically face challenges.
Speed comparison
RTT (Round Trip Time) is the time it takes for a message to pass back and forth between two participants in a connection. For example, between a client and a server. The fewer message exchanges (round-trips) it takes for the protocol to establish a connection, the less time it will take before the VPN can start sending user traffic.
| Wireguard (UDP) | Wireguard (in TLS tunnel) | AdGuard VPN (TLS) | OpenVPN (UDP) | OpenVPN (TCP) |
|---|---|---|---|---|
| 1 RTT | 3 RTT | 2 RTT | 4 RTT | 4 RTT |
AdGuard VPN now avoids unnecessary round-trips when establishing a connection, reducing their number from 4 to 2. 2 RTT is the best result you can get with a TLS-based protocol (which is what AdGuard VPN uses) so now you can get online as soon as possible.
Why is it important?
Connecting to servers quickly is key to a great user experience. Thanks to this change, we’ve reduced connection times to fractions of a second. This should be especially noticeable in countries where VPNs are restricted and users may have used to deal with longer connection times.
Faster connection to the server also makes AdGuard VPN work better when you're connected to an unstable network, or when you're switching between Wi-Fi and cellular.
And as a small but welcome side effect, the fewer rounds it takes to connect, the less likely it is that your ISP will notice you're using a VPN.
Other changes
In addition to speed, we’ve also worked on the appearance of the app — fixing several minor bugs in the interface of the mobile and TV versions.
