Fastest VPNs Compared
CyberGhost Speed Test Results
CyberGhost ranked #10 of 22 VPNs tested, delivering 612 Mbps throughput with 25 ms latency. Packet loss measured 0.2% with ±38 Mbps stability variance. It handles streaming and browsing without issues but falls short of the fastest VPNs for bandwidth-heavy tasks like large file transfers and competitive gaming.
Speed Results by Protocol
Protocol choice determines your CyberGhost experience more than server location. We tested all three supported protocols on a 1 Gbps fiber connection to the same server.
WireGuard delivered the best results at 612 Mbps average throughput with 25 ms latency. Connection time averaged 1.2 seconds. This protocol should be your default for nearly every use case.
IKEv2 came in second at 498 Mbps with 29 ms latency. Stability was tighter at ±22 Mbps variance. IKEv2 handles network switching better, making it useful on mobile devices that bounce between WiFi and cellular.
OpenVPN UDP hit 341 Mbps with 38 ms latency. OpenVPN TCP dropped further to 287 Mbps with 44 ms latency. These protocols remain relevant only when you need maximum compatibility or firewall bypass capabilities.
Performance Across Network Types
Fiber (1 Gbps Baseline)
CyberGhost retained 61.2% of our baseline speed on fiber. WireGuard peaked at 648 Mbps during burst transfers. Sustained downloads settled around 612 Mbps after the first 30 seconds.
Cable (300 Mbps Baseline)
On cable, throughput hit 247 Mbps, retaining 82.3% of baseline speed. The lower starting bandwidth means less encryption overhead as a percentage. Most users on cable connections will notice minimal slowdown during daily browsing.
Public WiFi (50 Mbps Baseline)
Public WiFi tests returned 41 Mbps through CyberGhost. Latency jumped to 52 ms due to the shared network environment. The encryption overhead consumed roughly 18% of available bandwidth on these slower connections.
Mobile (5G, 200 Mbps Baseline)
5G testing with IKEv2 produced 158 Mbps throughput. Network handoffs between towers caused 3 brief disconnections over 60 minutes. WireGuard reconnected faster at 0.8 seconds versus 2.1 seconds for IKEv2 after signal drops.
Streaming Performance
CyberGhost offers dedicated streaming servers optimized for specific platforms. We tested 4K playback stability across 4 services over 2 hours each.
4K streaming requires roughly 25 Mbps of sustained throughput. CyberGhost delivered 89 Mbps average to US streaming servers with buffer events occurring 0 times during our Netflix test. Bitrate remained locked at maximum quality after an initial 4-second negotiation period.
Disney Plus and Amazon Prime Video performed similarly with 78 Mbps and 84 Mbps respectively. YouTube 4K peaked at 112 Mbps on streaming-optimized servers. Standard servers delivered 12-18% lower throughput to the same regions.
The dedicated streaming servers reduced latency by 8 ms compared to standard servers in the same location. This translated to faster initial loading but identical sustained playback quality.
Gaming Latency
Competitive gamers need latency under 50 ms and packet loss below 0.5%. CyberGhost meets both thresholds on nearby servers but struggles at distance.
Local server ping averaged 25 ms, adding roughly 8 ms over our bare connection. Cross-continent connections (US East to EU West) jumped to 94 ms. Jitter measured 4.2 ms locally and 11.7 ms on transatlantic routes.
The 0.2% packet loss rate translates to roughly 1 dropped packet per 500 sent. For casual gaming, this is imperceptible. For ranked competitive play in titles like Valorant or CS2, the added latency and jitter put you at a measurable disadvantage compared to no-VPN connections.
Torrenting Throughput
CyberGhost provides dedicated P2P servers in 60 countries. Average download speed on well-seeded torrents reached 54 MB/s (432 Mbps) using WireGuard.
Upload speeds capped at 38 MB/s (304 Mbps) on the same servers. Connection to the P2P servers added 2.3 seconds versus standard server connections. Port forwarding is not available, which limits seeding ratios for users who prioritize upload performance.
A 10 GB test file completed in 3 minutes 5 seconds through CyberGhost versus 1 minute 22 seconds on our bare connection. That represents a 2.25x time increase for large downloads.
How CyberGhost Compares to the Top 5
| VPN | Throughput | Latency | Packet Loss | Stability |
|---|---|---|---|---|
| NordVPN (#1) | 891 Mbps | 14 ms | 0.1% | ±12 Mbps |
| Surfshark (#2) | 869 Mbps | 16 ms | 0.1% | ±15 Mbps |
| ExpressVPN (#3) | 824 Mbps | 18 ms | 0.1% | ±18 Mbps |
| PIA (#4) | 798 Mbps | 19 ms | 0.1% | ±20 Mbps |
| Proton VPN (#5) | 761 Mbps | 21 ms | 0.2% | ±24 Mbps |
| CyberGhost (#10) | 612 Mbps | 25 ms | 0.2% | ±38 Mbps |
CyberGhost trails the top performer by 279 Mbps. The ±38 Mbps stability variance is the most notable gap. Top-ranked VPNs hold speed within tighter bands, producing more consistent experiences during long sessions.
The latency difference of 11 ms versus NordVPN matters primarily for gaming and video calls. For streaming, browsing, and general downloading, CyberGhost’s 612 Mbps exceeds practical requirements by a wide margin.
Testing Methodology
All tests ran on a dedicated machine with a 1 Gbps symmetric fiber connection. We used a wired Ethernet connection to eliminate WiFi variability. Each test repeated 15 times across 3 different time periods (morning, afternoon, evening) over 5 days.
Speed measurements used iPerf3 and Ookla Speedtest CLI in parallel. Latency figures come from ICMP ping tests to 10 global endpoints averaged over 500 samples. Packet loss calculations used 10,000 packet samples per server tested.
We tested the 3 nearest servers and 5 international servers per protocol. The figures reported reflect the best-performing nearby server to simulate realistic usage patterns. All apps were updated to the latest version at time of testing.
Frequently Asked Questions
What does CyberGhost’s “#10 of 22” Speed Lab rank actually mean?
CyberGhost ranks #10 of 22 in our Speed Lab, aggregated from independent labs, placing it in the middle tier for throughput and latency among tested VPNs. The rank reflects testing across protocols (WireGuard, IKEv2, OpenVPN), network types including fiber, cable, public WiFi, and 5G, and use cases like streaming, gaming, and torrenting rather than a single number.
Which protocol delivers the fastest speeds on CyberGhost?
WireGuard performed best in testing, connecting in about 1.2 seconds and outperforming both alternatives. IKEv2 came in second with tighter stability, making it useful for mobile devices switching between WiFi and cellular. OpenVPN UDP and the slower OpenVPN TCP trail both and are best reserved for firewall bypass or maximum compatibility scenarios.
How much speed do I lose on CyberGhost over public WiFi versus fiber?
CyberGhost retained about 61.2% of baseline speed on a 1 Gbps fiber connection, but public WiFi fared worse, where encryption overhead consumed roughly 18% of available bandwidth. Cable connections held up better, retaining 82.3% of baseline. The gap widens on WiFi because its shared, lower-bandwidth environment leaves less room to absorb encryption overhead.
Can CyberGhost stream 4K content without buffering?
Yes. Across four platforms including Netflix, Disney+, and Prime Video tested over two-hour sessions, CyberGhost produced zero buffering events on its dedicated streaming servers, with playback locked at maximum bitrate after a brief initial negotiation. Those dedicated servers also loaded content faster than standard servers in the same region, though sustained playback quality matched either way.
How does CyberGhost’s torrenting speed compare to a direct connection?
CyberGhost runs dedicated P2P servers, but they add measurable overhead versus an unprotected connection. Connecting to a P2P server added about 2.3 seconds versus a standard server, and a 10 GB test file took roughly 2.25 times longer than over a bare connection. Port forwarding isn’t offered, which can limit seeding ratios for upload-focused users.
Is CyberGhost’s speed reliable enough for competitive gaming?
It clears the basic thresholds for competitive play on nearby servers, holding packet loss at 0.2%, or roughly one dropped packet per 500 sent. Jitter climbs noticeably on cross-continent routes like US East to EU West, though, and the added latency versus a direct connection puts ranked titles like Valorant or CS2 at a measurable disadvantage over long distances.
Does CyberGhost sacrifice encryption strength to achieve its speed results?
No. CyberGhost maintains AES-256 encryption and a functioning kill switch across every protocol tested, with no security tradeoff for performance. Its no-logs policy has been independently audited by Deloitte, and the company operates under Romanian jurisdiction. NoSpy servers, company-owned infrastructure located in Romania, are available for users wanting an extra layer of assurance.
Is CyberGhost’s speed worth its price compared to NordVPN?
CyberGhost ranks #10 of 22 in our Speed Lab versus NordVPN’s #1 spot, and NordVPN also costs more, from $3.49/month on its longest plan versus CyberGhost’s from $2.03/month. If raw throughput for gaming or large transfers matters most, NordVPN’s rank justifies the premium; for streaming and everyday browsing, CyberGhost’s lower price covers most practical needs.
What if CyberGhost’s real-world speed doesn’t meet my expectations?
You can request a refund within CyberGhost’s 45-day money-back guarantee, longer than the 30-day windows NordVPN and ExpressVPN both offer. That gives enough time to test WireGuard performance across fiber, cable, and mobile connections before deciding whether to keep the plan at its discounted from $2.03/month long-term rate.
Does connecting multiple devices slow down CyberGhost’s performance?
Not inherently. A CyberGhost account supports up to 7 simultaneous device connections, and each device negotiates its own server session rather than drawing from one shared bandwidth pool. Throughput on any single device depends far more on protocol choice, since WireGuard led testing, and on network type than on how many devices are connected at once.
How do I configure CyberGhost for the fastest possible connection?
Select WireGuard as your protocol, since it delivered the top results in testing and reconnected fastest, in about 0.8 seconds, after a dropped signal. Use Quick Connect to auto-select a nearby server, since proximity affects performance more than any other single setting. A wired Ethernet connection also outperformed WiFi in testing for bandwidth-heavy transfers.
What should I do if CyberGhost disconnects or slows on mobile networks?
Switch to WireGuard if you haven’t already. It reconnected in about 0.8 seconds after signal drops during 5G testing, versus 2.1 seconds for IKEv2, in a session where tower handoffs caused three brief disconnections over 60 minutes. If drops persist, try a nearer server, since tower handoff rather than the app itself usually causes the interruption.
