What determines VPN speed
VPN speed depends on several factors, and understanding them helps you get the best performance:
- Protocol — WireGuard is significantly faster than OpenVPN (30-50% in most benchmarks). It uses modern cryptography and has a minimal codebase that reduces processing overhead
- Server distance — the closer the server, the lower the latency. A server in your region typically adds 5-15ms, while a server across the ocean adds 100-200ms
- Server load — overloaded servers slow everyone down. Quality VPN providers monitor load and distribute users across available servers
- Your base connection — a VPN cannot make your internet faster than your ISP provides. On a 100 Mbps connection, expect 90-95 Mbps through VPN
WireGuard vs OpenVPN: speed comparison
In 2026, protocol choice is the single biggest factor in VPN speed:
- WireGuard — ~4,000 lines of code, runs in the kernel, uses ChaCha20 encryption. Typical throughput: 500-900 Mbps on modern hardware. Connection time: under 1 second
- OpenVPN — ~100,000 lines of code, runs in userspace, uses OpenSSL. Typical throughput: 200-400 Mbps. Connection time: 5-15 seconds
- VLESS — designed for environments with traffic analysis. Slightly slower than WireGuard due to additional obfuscation, but faster than OpenVPN
ProstoVPN uses WireGuard as its primary protocol, with VLESS available as an alternative. The app automatically selects the best option for your network.
How ProstoVPN maximizes speed
- 1 Gbps server channels — every server has at least 1 Gbps dedicated bandwidth
- Load balancing — traffic is automatically distributed across servers to prevent overload
- Smart routing — local services bypass the VPN tunnel entirely, so you only route through VPN what actually needs it
- Server locations in Europe, US, UK, Singapore — connect to the nearest server for the lowest latency
- Hardware AES acceleration — on devices with hardware crypto support (Apple Silicon, modern x86), encryption adds near-zero CPU overhead
Часто задаваемые вопросы
Will a VPN slow down my internet?
With WireGuard, expect 3-5% overhead at most. On a 100 Mbps connection, you'll typically see 90-95 Mbps through VPN. The difference is imperceptible for browsing, streaming, and most tasks.
Which server should I connect to for the best speed?
The nearest one. From Europe, connect to Netherlands or Germany. From the US, choose the US server. Lower distance means lower latency and higher throughput.
Can I stream 4K video through VPN?
Yes. 4K streaming requires 35-45 Mbps. ProstoVPN servers support up to 1 Gbps, so streaming performance is not an issue. Choose a server with ping under 50ms for the best experience.
