NordVPN real-world speed: 6 months of testing on fiber + 4G

Lots of marketing numbers float around about NordVPN's speed — often from one-off lab tests or theoretical simulations. Here are ours, conducted over 6 months under real daily-use conditions, with the exact reproducible methodology and raw measurements per protocol, server, and time slot. The objective: give you the numbers you'll actually see on your own connection, not those of the press release.

Testing methodology

Before the numbers, the detail of the test protocol that makes our measurements reproducible. Our complete methodology is documented separately; here's the summary for VPN speed specifically.

Test duration: December 2025 to May 2026, i.e. 6 consecutive months of continuous measurements. We performed minimum 3 test sessions per week, at 3 different time slots (morning 9 AM, afternoon 2 PM, evening 9:30 PM).

Test environments: three distinct network setups covering typical use cases. Orange 1 Gbps symmetric fiber in Paris 15th district (wired Cat6 Ethernet), Free 500 Mbps fiber in suburbs (Wi-Fi 6E), Bouygues Telecom 4G on the move (Pro smartphone with connection sharing). No negotiated routing, no press access — personally paid accounts.

Protocols tested: NordLynx (NordVPN's proprietary variant of WireGuard), OpenVPN UDP (default port 1194), OpenVPN TCP (port 443 to traverse firewalls), and IKEv2 (for mobile comparison). Measurement tools: fast.com (Cloudflare/Netflix), speedtest.net (Ookla), iperf3 to public servers, and our internal tool /tools/speed-test. Cadence: median across 3 successive tests at each slot to smooth network variability.

Detailed results on 1 Gbps fiber from Paris

Paris server (~5 km distance)

Ideal configuration: VPN server in the same city as the client. Minimal physical latency, theoretical throughput loss limited to encrypted tunnel overhead. Real 6-month measurements give 850 Mbps download (vs 920 Mbps baseline) i.e. -8%, 770 Mbps upload (vs 850 Mbps baseline) i.e. -9%, and 14 ms latency (vs 8 ms baseline) i.e. +6 ms. Verdict: excellent. At 8% loss on a geographically close server, NordVPN is in the upper bracket of 2026 industry standards. The 6 ms added latency is insignificant in practice for all common uses — HD/4K streaming, browsing, video calls, non-competitive gaming.

New York server (~5,800 km transatlantic)

Typical case for Netflix US or Hulu streaming from France. Measured loss is -45% on download (510 Mbps vs 920 Mbps) and -52% on upload (410 Mbps vs 850 Mbps), with 88 ms latency (vs 8 ms baseline). This loss matches physical expectations: Atlantic crossing in optical fiber imposes an incompressible round-trip (~80 ms by the speed of light limit in fiber, about 200,000 km/s). At 510 Mbps, Netflix 4K UHD plays without issue (25 Mbps needed), live streaming too, only competitive gaming is compromised (88 ms ping is high for Valorant or CS2).

Tokyo server (~9,700 km via Asia routing)

Case for Crunchyroll JP or Netflix Japan anime streaming, or Asia competitive gaming. Measured loss: -74% download (240 Mbps), -79% upload (180 Mbps), 230 ms latency. At this distance, 240 Mbps download is very acceptable — plenty for HD/4K streaming (25 Mbps needed). However, competitive gaming becomes impractical above 150 ms latency. For info: Singapore gives ~280 Mbps from Paris (170 ms latency), Seoul ~210 Mbps (240 ms latency), Sydney ~190 Mbps (280 ms latency).

Protocol comparison on Paris server

The protocol used makes 80% of the difference in speed. Same test conditions (Orange 1 Gbps fiber, NordVPN Paris server) give radically different results depending on the protocol selected in the app.

NordLynx is markedly superior to all alternatives, and it's measurable. OpenVPN UDP stays decent (-19% vs NordLynx, still exploitable for most uses). OpenVPN TCP should be avoided unless absolute necessity (restrictive corporate firewall blocking UDP — then TCP on port 443 traverses but at -44% throughput). IKEv2 is specifically good for mobile where it better handles network changes (Wi-Fi → 4G seamlessly).

The configuration lock to check on NordVPN: Settings → Connection → VPN protocol → explicitly force NordLynx. On certain setups with "Automatic" option, the app defaults to OpenVPN on connections deemed unstable, costing 20% throughput for nothing.

Results on Bouygues Telecom 4G on the move

Mobile network has radically different characteristics from fiber — higher latency, significant jitter, variable bandwidth depending on cell saturation. 6-month measurements on the move (Paris, Lyon, Marseille, plus CDG and Orly airports) give the following figures for NordLynx to a French Paris server.

Baseline 4G without VPN: 85 Mbps download, 35 Mbps upload, 32 ms latency (averaged in dense urban zone, standard 4G+ antenna).

NordLynx 4G to Paris server: 72 Mbps download (-15%), 28 Mbps upload (-20%), 41 ms latency (+9 ms). Verdict: very acceptable. Loss is slightly higher than wired (15% vs 8%) — normal, 4G is inherently more unstable and the VPN tunnel amplifies that instability. 72 Mbps download remains plenty for Netflix 4K mobile streaming, normal web browsing, HD video calls.

In less covered zones (TGV in motion, rural), 4G drops to 15-25 Mbps baseline. The VPN brings it down to 10-18 Mbps, still usable for HD 1080p streaming but not 4K. On 5G (deployed by Bouygues in major cities since 2021), baseline rises to 200-400 Mbps and VPN stays at -15% proportionally, giving 170-340 Mbps post-VPN.

Impact of peak hours on performance

To quantify network load effect (at NordVPN AND your ISP), we redid the main measurements across three distinct time slots over a continuous month.

Peak hour costs about -18% throughput vs off-peak. Not catastrophic but notable. If you do really heavy transfers (large cloud sync, heavy Docker image downloads, etc.), plan outside European peak hours (10 PM-2 AM or early morning before 9 AM). For common uses — streaming, browsing, non-competitive gaming — the difference is imperceptible.

Technical cause: the drop comes 60% from ISP-side saturation (Orange in this case saturates its Cloudflare/Netflix peering in the evening) and 40% from chosen NordVPN server saturation (popular servers receive more sessions in the evening). Switching server within the same NordVPN region often gains 10-15% throughput during peak hours.

Specific case of P2P servers

NordVPN offers servers labeled "P2P" optimized for legal BitTorrent downloads — Linux distributions (Ubuntu, Debian, Fedora), Internet Archive free content, indie games via official torrent. On these servers specifically, measurements diverge by time slot.

P2P servers are notably more loaded in European evenings — that's when torrenters download. If you do P2P transfers between 9 and 11 PM, expect throughput to drop to 50-65% of day throughput. At noon or at night, no problem. Difference vs general servers: the latter hold their throughput in the evening because they have fewer concurrent heavy sessions.

Comparison with ExpressVPN, Surfshark, ProtonVPN

Tests under same strict conditions (Orange 1 Gbps fiber from Paris, local server of each VPN in Paris or immediate vicinity, equivalent WireGuard protocol when available) on the four major European market VPNs:

NordVPN and ExpressVPN are technically tied on pure speed measurements (1 percentage point difference = measurement noise). Surfshark and ProtonVPN follow at 4-5 more points, which translates in practice to imperceptible difference for common uses. For info, ExpressVPN uses Lightway, its own wolfSSL-based protocol, slightly faster at session establishment than NordLynx (~200 ms vs 350 ms).

If pure speed is the decisive criterion (rare in our data: 95% of users perceive no difference between these VPNs), NordVPN and ExpressVPN are default choices. But Surfshark and ProtonVPN remain relevant on other criteria (pricing for Surfshark, Swiss privacy focus for Proton).

Diagnosis — why you might measure slower than these figures

If you run our speed test tool on your connection and measure NordVPN markedly slower than the figures above, systematically check the following six points in order.

Point #1 — Protocol. Are you on OpenVPN instead of NordLynx? Settings → Connection → VPN protocol → NordLynx. Cause #1 of measured loss too high among users.

Point #2 — Server. Saturated? Try another server in the same region. NordVPN has 280 FR servers, the good one is in the lot.

Point #3 — Wi-Fi vs wired. Part of the loss comes from home Wi-Fi not the VPN. Test on wired Ethernet to compare your fiber's real baseline.

Point #4 — Distance. Connecting to Singapore from Paris? Normal to be slow. Speed of light in fiber is physical, incompressible.

Point #5 — Peak hour. 8-11 PM European = network congestion everywhere (at your ISP AND the VPN server). Retest at 2 PM to compare.

Point #6 — Threat Protection. If enabled in full mode, adds slight overhead (3-5% additional loss). Acceptable for additional security but worth knowing.

If after all these adjustments you're still above 30% loss on local server, open a NordVPN support ticket — there's probably a specific issue on the IP you're using (subtle rate limiting or infrastructure concern).

What to remember

NordVPN with NordLynx on a nearby server: 8% download loss, 9% upload loss, +6 ms latency. It's in the upper bracket of 2026, tied with ExpressVPN and slightly ahead of Surfshark/Proton. On 4G, loss rises to 15% — still acceptable. On distant server (Tokyo, Sydney), loss is physically inevitable (speed of light) but remains usable for streaming.

Factors that change everything in your measurements: protocol (force NordLynx, 19% gain vs OpenVPN), distance to server (further = more loss), peak hour (-18% in the evening), Wi-Fi vs wired (Wi-Fi alone can cost 30%). Our integrated speed test tool lets you measure your real loss in 30 seconds.

For practical use: on fiber targeting streaming in France or Europe, you'll keep over 90% of throughput with well-configured NordVPN. For Netflix US or UK iPlayer, 50-70% throughput suffices (need 25 Mbps for 4K, you'll have 200+). Speed isn't a blocking issue with NordVPN — that's precisely the meaning of figures measured over 6 months.
