How much does a VPN slow down your internet?

With modern WireGuard-based VPNs, you'll typically see only 5–15% speed reduction on nearby servers. Older OpenVPN protocols can cut speed by 30–50%. Server distance is the biggest variable.

Which VPN is fastest in 2026?

NordVPN (NordLynx), Mullvad, and ExpressVPN (Lightway) consistently top speed tests in 2026. The gap has narrowed significantly — your nearest server location matters more than the brand.

Does VPN speed matter for streaming?

For HD streaming you need at least 25 Mbps; 4K needs 50+ Mbps. Any top-tier VPN far exceeds this. Latency matters more for gaming — aim for under 50ms to the game server.

Is free VPN speed good enough?

Free VPN plans (ProtonVPN free, Windscribe free) throttle speeds and limit server choice. They're fine for occasional light browsing but poor for streaming, gaming, or large downloads.

VPN Speed Test Deep Comparison 2026: Which VPN Is Actuall...

The short answer: with WireGuard, a good VPN costs you almost nothing in speed on nearby servers. The real question is which VPN holds up on international connections — and that’s where the differences get interesting.

We ran over 200 speed tests across 4 VPN providers, 4 server locations, and 3 times of day. Here’s what we found.

How We Tested VPN Speeds

Test Setup

Baseline connection: 1 Gbps fiber (Comcast, Chicago)
Tools: Speedtest.net CLI, fast.com, iPerf3
Test times: 9 AM, 2 PM, 9 PM on weekdays
Repetitions: 5 runs per server, averaged
Protocol: WireGuard where available, provider default otherwise

What We Measured

Download speed (Mbps)
Upload speed (Mbps)
Ping/latency (ms)
Speed retention (% of baseline)

We deliberately avoided cherry-picking best-case results. Averages, not peaks.

NordVPN — The All-Rounder

NordVPN uses NordLynx, their WireGuard implementation. It’s been the benchmark for speed since 2024.

Chicago server (local)

Download: 948 Mbps (94.8% retention)
Upload: 881 Mbps
Ping: 4ms

London server

Download: 510 Mbps (51% retention)
Ping: 98ms

Tokyo server

Download: 340 Mbps (34% retention)
Ping: 162ms

Local performance is exceptional. International servers drop more than competitors, but 340 Mbps to Tokyo is still more than enough for any practical use.

ExpressVPN — Best for International Use

ExpressVPN’s Lightway protocol is purpose-built for speed and reconnection. Where it truly shines is on long-haul connections.

Chicago server (local)

Download: 921 Mbps (92.1% retention)
Ping: 6ms

London server

Download: 580 Mbps (58% retention)
Ping: 95ms

Tokyo server

Download: 430 Mbps (43% retention)
Ping: 155ms

Tokyo and London results beat NordVPN. If you regularly connect to servers in Asia or Europe, ExpressVPN holds up better over distance.

Mullvad — Privacy Without Sacrificing Speed

Mullvad doesn’t ask for your email or personal info. Despite the privacy focus, speeds are competitive.

Chicago server (local)

Download: 910 Mbps (91% retention)
Ping: 5ms

London server

Download: 490 Mbps (49% retention)
Ping: 101ms

Mullvad’s local speeds are nearly tied with the big names. It falls slightly behind on international routes but remains fast enough for any practical need.

At $5/month flat (no annual contract games), Mullvad offers the best value per dollar if privacy is your priority.

Surfshark — Budget Pick With Solid Speed

Surfshark covers unlimited devices — useful if you’re installing on every phone, laptop, and tablet in the house.

Chicago server (local)

Download: 886 Mbps (88.6% retention)
Ping: 9ms

London server

Download: 445 Mbps (44.5% retention)
Ping: 104ms

Slightly behind the top three on local speeds, but the gap is negligible for everyday use. Long-term plans bring the price under $3/month.

ProtonVPN — The Trustworthy Option

ProtonVPN comes from the same team as ProtonMail. Audited no-log policy, Swiss jurisdiction, open-source apps.

Chicago server (paid plan)

Download: 840 Mbps (84% retention)
Ping: 12ms

London server

Download: 390 Mbps (39% retention)
Ping: 108ms

Slightly slower than the others, but the trust factor is unmatched. ProtonVPN also offers a genuinely usable free tier with 3 server locations.

Speed Comparison at a Glance

VPN	Local Download	Local Ping	London	Tokyo	Price/mo
NordVPN	948 Mbps	4ms	510 Mbps	340 Mbps	$3.99
ExpressVPN	921 Mbps	6ms	580 Mbps	430 Mbps	$6.67
Mullvad	910 Mbps	5ms	490 Mbps	—	$5.00
Surfshark	886 Mbps	9ms	445 Mbps	310 Mbps	$2.49
ProtonVPN	840 Mbps	12ms	390 Mbps	—	$4.99

What Actually Affects VPN Speed?

Protocol Matters Most

WireGuard / NordLynx / Lightway — fastest, modern
IKEv2 — fast, good for mobile
OpenVPN — slower but most compatible
L2TP/IPSec — avoid, outdated

Always check your app settings and force WireGuard if available.

Server Load

A server with 500 users is slower than one with 50. Most apps show load percentage — pick servers under 30% load when speed matters.

Your ISP Throttling

Some ISPs throttle VPN traffic. If speeds are suspiciously low, try switching ports or using obfuscation mode (NordVPN Obfuscated, ExpressVPN Lightway UDP).

Tips to Speed Up Your VPN

Switch to WireGuard in protocol settings
Pick the closest server — auto-connect isn’t always optimal
Use split tunneling — route only sensitive traffic through VPN
Update the VPN app — performance patches come regularly
Test at different times — peak hours (7–11 PM) are slower on any server

Bottom Line: Which VPN Should You Choose?

For raw speed: NordVPN or Mullvad on local/nearby servers.

For international streaming or gaming: ExpressVPN wins on long-haul connections.

For best value: Surfshark — unlimited devices, solid speeds, lowest long-term price.

For privacy-first users: Mullvad (no account needed) or ProtonVPN (audited, open-source).

All four top picks offer 30-day money-back guarantees. Run your own speed test before committing — your ISP and location will produce different results than ours.
