Test Methodology
We conducted controlled benchmarks across 12 VynVPN server regions over 30 days, measuring:
- **Latency** (p50, p95, p99)
- **Throughput** (sustained download/upload)
- **Connection establishment time**
- **Reliability under DPI** (connection success rate in restricted networks)
All tests used identical hardware (AWS c5.xlarge instances) with 1Gbps network interfaces.
Latency Results
Without DPI
| Protocol | p50 | p95 | p99 |
|---|---|---|---|
| WireGuard | 12ms | 18ms | 24ms |
| VLESS | 14ms | 21ms | 28ms |
WireGuard wins on raw latency by 2-4ms due to its kernel-level implementation. For most applications, this difference is imperceptible.
Under DPI
| Protocol | p50 | p95 | p99 |
|---|---|---|---|
| WireGuard | Blocked | Blocked | Blocked |
| VLESS | 16ms | 25ms | 34ms |
WireGuard's distinctive packet signatures make it trivially blockable by DPI. VLESS continues operating with only marginal latency increase.
Throughput Results
Download (1Gbps available)
| Protocol | Average | Peak |
|---|---|---|
| WireGuard | 890 Mbps | 940 Mbps |
| VLESS | 820 Mbps | 880 Mbps |
Upload (1Gbps available)
| Protocol | Average | Peak |
|---|---|---|
| WireGuard | 870 Mbps | 920 Mbps |
| VLESS | 790 Mbps | 850 Mbps |
WireGuard achieves ~8% higher throughput due to its simpler packet structure and kernel integration.
The Verdict
Use WireGuard when you're on unrestricted networks and need maximum raw performance (gaming, large file transfers, video production).
Use VLESS when reliability matters more than the last 8% of throughput (business use, restricted networks, travel).
VynVPN's automatic protocol selection handles this decision for you — defaulting to VLESS for reliability and offering WireGuard as an option for users who prioritise speed on trusted networks.
