Fastest VPNs Compared
How Fast Is ProtonVPN?
ProtonVPN ranked #12 of 22 VPNs tested with 580 Mbps average throughput, 22 ms latency, and 0.2% packet loss. WireGuard delivered the best results. Speed stability fluctuated by ±25 Mbps during sustained transfers. ProtonVPN handles streaming and browsing well but falls behind the top 5 providers in raw throughput.
Speed Results by Protocol
Protocol choice changes ProtonVPN performance dramatically. We tested each protocol 15 times across 3 server regions.
WireGuard
WireGuard hit 580 Mbps download and 490 Mbps upload on a 1 Gbps fiber connection. Latency sat at 22 ms with consistent 0.2% packet loss. Connection handshake completed in under 1 second. This protocol delivered the most stable performance with only ±25 Mbps variation during 30-minute tests.
OpenVPN (UDP)
OpenVPN UDP reached 310 Mbps download and 260 Mbps upload on the same fiber connection. Latency jumped to 38 ms. Packet loss stayed at 0.3%. The throughput penalty compared to WireGuard was 46%. Connection establishment took 4-6 seconds on average.
OpenVPN (TCP)
OpenVPN TCP managed 240 Mbps download and 195 Mbps upload. Latency increased to 45 ms due to TCP overhead. This protocol works best when UDP traffic gets blocked on restrictive networks. Speed dropped 59% compared to WireGuard.
IKEv2
IKEv2 produced 420 Mbps download and 355 Mbps upload. Latency measured 28 ms. This protocol reconnects faster than OpenVPN after network switches. Mobile users benefit from IKEv2 when WireGuard is unavailable.
Performance Across Network Types
Network infrastructure affects VPN speed more than most users realize. We tested ProtonVPN on 4 common connection types.
Fiber (1 Gbps)
ProtonVPN retained 58% of baseline speed on fiber using WireGuard. The 580 Mbps ceiling means gigabit users lose significant throughput. Top-ranked VPNs retain 75-85% on the same connection. Fiber users notice the speed gap most.
Cable (300 Mbps)
Cable connections saw 255 Mbps download with WireGuard enabled. That represents 85% speed retention. ProtonVPN performs better on mid-range connections because the 580 Mbps throughput ceiling sits above the baseline. Most cable users will not notice significant slowdowns during daily use.
Public WiFi (50 Mbps)
Public WiFi tests returned 42 Mbps download and 35 Mbps upload. Speed retention reached 84%. Latency increased to 45 ms due to shared network congestion. ProtonVPN’s Secure Core feature added 15-20 ms additional latency on public networks.
Mobile (5G and LTE)
5G connections delivered 280 Mbps download through ProtonVPN WireGuard. LTE connections averaged 65 Mbps download. Battery consumption increased 12% with WireGuard active over 4 hours. IKEv2 handled network transitions between WiFi and cellular more smoothly than WireGuard.
Streaming Performance
ProtonVPN maintains enough bandwidth for 4K streaming on most connections. Netflix 4K requires 25 Mbps sustained throughput. ProtonVPN never dropped below 120 Mbps on fiber during our 2-hour streaming test.
Buffer-free 4K playback worked on US, UK, and Netherlands servers. Japanese and Australian servers showed 15% more throughput variation. Initial stream loading took 2-3 seconds longer than without a VPN. Bitrate stayed locked at maximum quality after the initial buffering period.
Gaming Latency
Gamers care about latency more than throughput. ProtonVPN added 12-18 ms to baseline ping on nearby servers. Connecting to servers within 500 miles kept total latency under 40 ms. Servers beyond 2,000 miles pushed latency to 80-120 ms.
Jitter measured 4 ms on WireGuard, which stays within acceptable limits for competitive gaming. Packet loss at 0.2% means roughly 1 dropped packet per 500 sent. First-person shooter players will notice this on occasion. Casual and turn-based games perform without issues.
Torrenting Throughput
ProtonVPN allows P2P traffic on designated servers in 9 countries. Torrent download speeds averaged 420 Mbps on WireGuard with well-seeded files. Upload throughput reached 350 Mbps. Port forwarding is not available, which limits seeding performance for some torrent clients.
Sustained 1-hour torrent sessions showed no throttling or speed degradation. The ±25 Mbps stability variance had minimal impact on large file transfers. ProtonVPN’s NetShield ad blocker reduced tracker connections by 30% during torrent sessions.
ProtonVPN vs. Top 5 Fastest VPNs
ProtonVPN’s 580 Mbps places it firmly in the middle tier. Here is how it compares to the 5 fastest VPNs we tested.
| VPN | Throughput | Latency | Packet Loss | Rank |
|---|---|---|---|---|
| #1 Provider | 850 Mbps | 14 ms | 0.1% | 1 |
| #2 Provider | 810 Mbps | 16 ms | 0.1% | 2 |
| #3 Provider | 780 Mbps | 18 ms | 0.1% | 3 |
| #4 Provider | 740 Mbps | 19 ms | 0.2% | 4 |
| #5 Provider | 700 Mbps | 20 ms | 0.1% | 5 |
| ProtonVPN | 580 Mbps | 22 ms | 0.2% | 12 |
ProtonVPN trails the fastest provider by 270 Mbps (32%). Latency differences stay small at 8 ms behind the leader. Packet loss matches 2 of the top 5 providers. The speed gap narrows significantly on connections under 500 Mbps.
Why ProtonVPN Ranks Mid-Pack
ProtonVPN prioritizes security features that cost speed. Secure Core routes traffic through 2 VPN servers instead of 1. This adds 40-60 ms latency and cuts throughput by 35%. Users who disable Secure Core gain measurable speed improvements.
ProtonVPN operates its own server infrastructure rather than renting third-party servers. This approach improves privacy but limits server count to 4,600 across 91 countries. Fewer servers means higher load during peak hours. Server congestion explains most user reports of ProtonVPN running slow.
Testing Methodology
All tests ran on a dedicated 1 Gbps symmetric fiber connection in a controlled lab environment. We used iPerf3 for throughput, ICMP ping for latency, and custom scripts for packet loss measurement. Each data point represents the median of 15 test runs.
We tested from 3 geographic locations to 10 ProtonVPN server regions. Tests ran during off-peak hours (2-4 AM local server time) and peak hours (7-9 PM). The results above reflect combined averages. Hardware included a Ryzen 7 5800X workstation with 32 GB RAM running Ubuntu 22.04.
Frequently Asked Questions
How fast is ProtonVPN compared to other VPNs on the market?
ProtonVPN ranks #12 of 22 in our Speed Lab, aggregated from independent labs, placing it solidly in the middle tier rather than among the fastest providers. WireGuard delivered the strongest results of the protocols tested, with packet loss holding steady at 0.2% throughout testing. It handles everyday streaming and browsing comfortably but trails the fastest half of the field in raw throughput.
Which protocol should I use for the best ProtonVPN speeds?
WireGuard delivers ProtonVPN’s fastest and most stable results, with connection handshakes completing in under a second. OpenVPN UDP runs roughly 46% slower than WireGuard, while OpenVPN TCP drops speed by about 59%, though TCP works best when UDP traffic gets blocked on restrictive networks. IKEv2 reconnects faster after network switches, making it a solid mobile fallback when WireGuard isn’t available.
Does turning on Secure Core noticeably slow ProtonVPN down?
Yes. Secure Core routes your traffic through two VPN servers instead of one for added privacy, and that extra hop cuts throughput by about 35% while adding noticeable latency overhead. Users who disable Secure Core see a measurable speed improvement. It’s a worthwhile tradeoff for high-risk privacy needs, but casual streaming or browsing users can usually skip it.
Can ProtonVPN reliably stream 4K content without buffering?
Generally yes, on the right servers. ProtonVPN maintained buffer-free 4K playback on US, UK, and Netherlands servers during testing, with bitrate locking at maximum quality after an initial 2-3 second loading delay. Japanese and Australian servers showed about 15% more throughput variation, so streaming consistency depends heavily on which server region you choose.
Why does ProtonVPN feel slower on gigabit fiber connections specifically?
ProtonVPN retained only about 58% of baseline speed on a 1 Gbps fiber connection using WireGuard, well below the 75-85% retention that top-ranked providers achieve on the same infrastructure. By contrast, ProtonVPN held onto 85% of baseline speed on cable and 84% on public WiFi, since its throughput ceiling sits comfortably above those lower baselines.
Is ProtonVPN’s speed tradeoff worth it for the privacy it offers?
For privacy-focused users, yes. ProtonVPN operates under Swiss jurisdiction with a strict no-logs policy independently audited by Securitum, and features like Secure Core add real protection by routing traffic through two servers rather than one. That security layer costs measurable throughput, but it’s a deliberate design choice rather than a performance shortfall.
Is ProtonVPN’s latency low enough for competitive online gaming?
It depends on server distance and game type. ProtonVPN adds latency on top of your baseline ping, with connections to nearby servers keeping totals low and servers over 2,000 miles away pushing latency noticeably higher. Packet loss sits at 0.2%, roughly one dropped packet per 500 sent, which casual and turn-based gamers won’t notice but competitive FPS players occasionally will.
How does ProtonVPN perform for torrenting large files?
ProtonVPN allows P2P traffic on designated servers across many countries and showed no throttling or speed degradation during sustained one-hour torrent sessions in testing. It doesn’t offer port forwarding, though, which limits seeding performance for some torrent clients. Its built-in NetShield ad blocker also reduced tracker connections by about 30% during torrent sessions.
Is ProtonVPN’s speed good enough given its price point?
ProtonVPN starts from $2.49/month on its longest-term plan, running 15,000+ servers across 120+ countries, and ranks #12 of 22 in our Speed Lab. Faster-ranked competitors like NordVPN and ExpressVPN price similarly at $3.49/month, so if raw throughput is your top priority, those options edge out ProtonVPN despite comparable entry pricing.
How can I verify ProtonVPN’s real-world speed on my own connection?
Run your own throughput and latency tests using a tool like iPerf3 for speed and ICMP ping for latency, testing at both off-peak and peak hours since server load varies. Our lab testing used this exact approach across 3 geographic locations connecting to 10 ProtonVPN server regions, with each result representing the median of 15 test runs.
What should I do if ProtonVPN feels slower than expected?
Switch your protocol to WireGuard first, since it consistently outperformed OpenVPN and IKEv2 in testing with only ±minor stability variation over 30-minute sessions. Disable Secure Core if it’s on, as it cuts throughput by roughly 35%. If a specific server feels congested, ProtonVPN’s own infrastructure model means server load during peak hours is a common cause of slowdowns.
Why does ProtonVPN drain my phone’s battery faster than expected?
WireGuard, while ProtonVPN’s fastest protocol, increased battery consumption by about 12% over 4 hours of active use in testing. If battery life matters more than peak speed on mobile, switch to IKEv2 instead, which also handles transitions between WiFi and cellular networks more smoothly than WireGuard during travel or commuting.
Can I test ProtonVPN’s speed before committing to a paid plan?
Yes. ProtonVPN backs every paid plan with a 30-day money-back guarantee, giving you a full month to run your own throughput and latency tests across different servers and protocols. If performance on your specific connection doesn’t meet your needs, whether for streaming, gaming, or torrenting, you can request a refund within that window.
