What is EdgeRouter X and why VPN throughput matters
The EdgeRouter X ER-X from Ubiquiti is a budget-friendly, feature-rich router aimed at home labs and small offices. It’s powered by a capable but modest CPU and offers five 1-Gigabit Ethernet ports, plus robust EdgeOS features for routing, NAT, firewall rules, and VPN endpoints. Because VPN processing is CPU-intensive, your VPN throughput on the ER-X will usually be lower than its raw LAN-to-WAN routing capacity. In practice, you’re balancing the incoming connection speed from your ISP, the encryption overhead of the VPN protocol, and the overhead of your firewall/NAT rules.
Key factors that shape VPN throughput on the ER-X:
- VPN protocol and encryption: OpenVPN is verbose and CPU-heavy. IPsec/IKEv2 is generally lighter. WireGuard is designed for speed but needs compatible support on EdgeOS.
- CPU load and core efficiency: The ER-X relies on a relatively modest dual/quad-core CPU for encryption tasks.
- Network path and MTU: Larger packets can crash performance if fragmentation happens. correct MTU sizing helps maintain stable throughput.
- Memory and storage contention: If EdgeOS processes and logging consume too much RAM, throughput can suffer.
- Connected devices and simultaneous sessions: More clients mean more cryptographic work and routing decisions.
VPN throughput basics on EdgeRouter X
Here’s what usually happens in real life:
- OpenVPN: Expect lower throughput due to the VPN’s heavy TLS/SSL overhead. Typical real-world OpenVPN throughput on ER-X ranges from roughly 20–60 Mbps with strong encryption like AES-256-CBC, depending on CPU load and client distance.
- IPsec/IKEv2: Since IPsec is generally more efficient on many CPUs, you’ll often see higher throughput than OpenVPN. Expect around 60–200 Mbps for common configurations, with lighter ciphers and PSK-based setups performing best.
- WireGuard: When EdgeOS supports WireGuard well on the ER-X, WireGuard can outperform both OpenVPN and IPsec because of its leaner protocol and faster cryptography. Real-world WireGuard throughput on a similar edge router can push toward 150–400+ Mbps under favorable conditions, but it heavily depends on kernel/module support and CPU optimization.
These ranges aren’t guarantees. they reflect typical reports from users with similar gear and configurations. Your numbers will vary based on cipher choices, VPN server location, and the exact firmware version of EdgeOS you’re running.
Real-world benchmarks and what they mean for you
- A typical OpenVPN setup with AES-256-CBC and SHA-1 authentication on a mid-range ER-X might give you 25–60 Mbps in a domestic scenario with a 200–400 Mbps ISP link. If you’re on a slower internet plan or you’re routing through a long distance, those numbers can drop further.
- IPsec in tunnel mode IKEv2/IPsec with AES-GCM can often reach 100–250 Mbps on the same hardware, provided your VPN server supports high-speed crypto and you’re not bottlenecked by the client’s uplink.
- WireGuard tests, where available, show potential for higher throughput on the ER-X, but results depend on whether your EdgeOS build has solid WireGuard support and whether you’re using a compatible peer. With well-tuned settings, you can see performance closer to your native WAN speed, though a tight budget router will still be a factor.
Pro tip: To maximize VPN throughput on the ER-X, keep your local network simple minimize extra firewall rules that must be checked on each packet, and don’t overfill the router with unnecessary foreground tasks while testing VPN performance.

How to measure Edgerouter X VPN throughput at home step-by-step
- Set a baseline for LAN-to-WAN throughput without VPN
- Connect a wired device to ER-X.
- Disable VPN features temporarily.
- Run a speed test against a reliable server preferably near your actual VPN targets to establish a baseline.
- Measure VPN throughput with OpenVPN
- Enable OpenVPN server or client on EdgeRouter X.
- Use a consistent test file for example, a 1 GB file and measure time to transfer with a speed test tool or iperf.
- Compare the VPN-encapsulated path to the baseline throughput.
- Measure VPN throughput with IPsec
- Set up IPsec IKEv2 with AES-GCM if possible, using a fast server nearby.
- Run the same test as above and compare.
- Measure VPN throughput with WireGuard if supported
- Enable WireGuard on the ER-X or via a compatible EdgeOS build.
- Run the same tests to see how WireGuard stacks up.
- Factor in latency and jitter
- Speed isn’t everything. VPNs add latency. Use ping tests and jitter measurements to ensure you’re not trading speed for stability.
- Benchmark across servers and times of day
- Run tests at different times to see how network congestion affects results. Use the same test method each time to keep comparisons fair.
- Document your results
- Keep notes on the exact cipher, protocol, server distance, and client device. This helps you replicate or adjust configurations later.
Optimization tips to boost Edgerouter X VPN throughput practical, for real life
-
Prefer IPsec or WireGuard where possible
- If your VPN provider supports IPsec IKEv2 with modern ciphers AES-GCM, you’ll likely see better throughput than OpenVPN on the ER-X.
- If WireGuard is available for EdgeRouter X and you have compatible support, it can dramatically improve throughput thanks to its lean protocol.
-
Tune MTU and fragmentation
- Start with an MTU around 1500 and adjust down by 10–20 bytes if you encounter packet loss or VPN instability. Fragmentation penalties kill throughput.
-
Simplify firewall and NAT rules during testing
- Temporarily reduce the rule set to essential connections. Each extra rule adds a small amount of processing per packet.
-
Use hardware acceleration where available
- Ensure the router’s hardware acceleration/fast path is enabled for IPsec or OpenVPN if your EdgeOS version supports it. This can give you a meaningful bump in throughput.
-
Upgrade to a more capable EdgeRouter model for demanding scenarios Browsec vpn free vpn for edge
- If you consistently require high VPN throughput 100–300+ Mbps per user, consider stepping up to a more powerful router in the EdgeRouter line like ER-6P or higher models or adding a dedicated VPN appliance behind the ER-X.
-
Prefer lighter ciphers and modes
- AES-GCM is generally faster and more secure than older modes like AES-CBC. If your server supports it, use AES-GCM for IPsec, and similarly favor modern OpenVPN cipher choices that are hardware-accelerated.
-
Ensure firmware is up to date
- EdgeOS updates can bring performance and stability improvements, especially for VPN components. Always back up configurations before upgrading.
-
Optimize VPN server placement
- Choose VPN servers that are geographically close and have low latency to your client location. The physical distance often matters more than you’d think for VPN throughput.
-
Plan your network layout
- Place VPN endpoints to minimize routing hops through the ER-X. A clean path reduces CPU work and helps throughput.
-
Use a dedicated VPN device or secondary router if needed How to open vpn in microsoft edge
- If you’re hosting multiple VPN clients or expect high throughput, consider running VPN on a dedicated device a small PC, a Raspberry Pi 4 with VPN server software, or a more powerful router and using ER-X as the edge device only.
Setup basics for common VPN types on EdgeRouter X
OpenVPN server or client
- Basics:
- In EdgeOS, you can set up an OpenVPN server or client directly in the VPN section. OpenVPN tends to be heavier on the CPU, so expect lower throughput for OpenVPN compared to IPsec.
- Quick tips:
- Use strong but efficient cipher configurations AES-256-GCM if supported.
- Keep the VPN daemon’s CPU usage in check by limiting simultaneous connections where possible.
IPsec/IKEv2
- IPsec/IKEv2 is generally more efficient than OpenVPN on consumer hardware.
- You can configure IPsec with pre-shared keys PSK or certificates, with AES-GCM as a practical default.
- Use a nearby VPN server to minimize latency.
- Consider disabling weaker encryption suites to reduce CPU time.
WireGuard if supported on EdgeOS
- WireGuard is designed for speed and simplicity. If your EdgeOS build supports it, WireGuard can offer substantial throughput gains.
- Ensure kernel/module support is current.
- Use a few strong peers and stable keys for predictable performance.
Testing and tuning sequence
- Start with baseline WAN throughput no VPN
- Add OpenVPN and test
- Switch to IPsec and test
- If available, test WireGuard
- Tweak MTU and firewall rules
- Re-test to measure improvements
