IEPL, relay, and direct are route descriptions, not guarantees of a particular speed. The terms indicate how traffic may travel between network points, but your result also depends on the access network, VPN server, destination, protocol, and time of day. A route that performs well for one destination or task may not perform equally well for another.
To compare routes use repeatable tests, separate latency from throughput, and note the conditions under which you tested. A single speed-test result cannot explain whether a connection will feel responsive in a game, sustain a video stream, or load ordinary websites reliably. This guide explains the terminology and gives you a practical way to compare routes without treating labels as performance promises.
IEPL, relay, and direct routes: what the labels mean
IEPL is commonly expanded as International Ethernet Private Line. In networking, it describes a private point-to-point connectivity service between network locations. A VPN provider may use an IEPL segment for part of the path between its network points, but the label alone does not establish that every segment from your device to the destination uses a private line. Your local access network, the connection to the provider’s first point of presence, the VPN exit, and onward internet routing still affect the result.
A relay route sends traffic through an intermediate server or network point before it reaches the next part of the path. Relaying can provide an alternate path when a simpler route is congested or unsuitable, but it adds another point whose capacity and routing matter. “Relay” does not say whether the intermediate segment is private, how many hops are involved, or whether the destination will be reached through a particular transit provider. Ask what the service means by the term if the distinction matters to your decision.
Direct usually means that traffic follows a path without the particular relay or intermediate step being compared. It does not necessarily mean that the traffic bypasses a VPN tunnel, that it travels in a straight geographical line, or that the route is always shorter. Internet routing is determined by network connectivity and policy, not by a map’s distance alone. A direct route can be efficient when its networks peer well; it can also perform poorly if the available path is congested or takes an indirect detour.
| Route label | What it generally describes | Potential benefit | What the label does not prove |
|---|---|---|---|
| IEPL | A private point-to-point network segment used between locations. | May offer a more controlled segment than ordinary public transit between those points. | That the full path is private, uncongested, or faster for every destination. |
| Relay | Traffic passes through an intermediate network point. | May provide an alternate route when another path is unsuitable. | That the extra hop improves performance or uses a particular type of link. |
| Direct | Traffic avoids the specific relay step under comparison. | May reduce unnecessary intermediate handling where the path is already good. | That the route is geographically shortest, uncrowded, or low-latency. |
In practice, route names are most useful as a starting point for testing. Check the actual endpoints and test destination, then compare performance under similar conditions. If you are reviewing a provider’s route options, the VPNWear VPN for China homepage is one place to check the service context; its route label should still be assessed separately from your own network results.
Read speed tests as separate measurements
Speed-test pages often reduce a connection to a few numbers, but those numbers answer different questions. Record latency, jitter, packet loss, download throughput, and upload throughput separately. A route can have strong download throughput and still feel unresponsive in an interactive application if latency varies or packets are lost. Conversely, a higher latency result may be acceptable for downloading a large file if the connection remains stable and has enough throughput.
- Latency: The time taken for a packet to travel to a test endpoint and for a response to return, usually reported as round-trip time. Lower latency can make interactive actions feel more immediate, but the result applies to that endpoint and test moment.
- Jitter: Variation in packet delay. Consistent delay is often more useful for real-time voice or gameplay than a single favorable latency reading that changes significantly from one test to the next.
- Packet loss: Packets that fail to reach the destination or return. Loss may trigger retransmissions or disrupt real-time traffic. A browser speed test may not make intermittent loss obvious, so compare repeated results and check application behavior.
- Download throughput: The rate at which data arrives. It matters for downloads and video delivery, but a short test may not represent a long session or a busy period.
- Upload throughput: The rate at which data leaves your device. It matters for calls, livestreaming, file backups, and sending large attachments, even when download speed looks strong.
For a fair comparison, keep the test device, access network, test server, VPN mode, and approximate test duration consistent. If one route is tested over Wi-Fi and another over a wired connection, the results mix route performance with access-network differences. Close heavy transfers and background backups where practical. Do not compare a test against a nearby endpoint on one route with a distant endpoint on another and treat the difference as a route-only result.
Use more than one test destination if your normal work involves different services. A speed-test server is only one endpoint, and its network relationship to the VPN exit may be unusually favorable or unfavorable. For a video service, test playback itself. For a game, observe in-game latency and stability to the relevant game region. For browsing, check page loading and DNS behavior. These application-level checks complement, rather than replace, network measurements.
A speed-test result describes a connection to a particular test server at a particular time. It is not a universal score for every app, region, or hour of the day.
Also check whether the client is using a full tunnel, system proxy, or application-specific routing mode. These modes can send different traffic through the VPN. A test that bypasses the tunnel cannot be used to judge the VPN route, while a test routed through the VPN may not represent an app that follows different rules. Confirm the active mode and the test app’s routing before drawing conclusions.
A hands-on method for comparing routes
Run the comparison in a way that makes it possible to repeat. You do not need specialized equipment, but you do need to keep notes. Record the selected route, client mode, network type, test endpoint, date and time, and the measurements you can obtain. Avoid changing several settings between runs: if you switch route, protocol, device, and Wi-Fi network together, you will not know which change influenced the outcome.
- Choose a real task. Decide whether you are evaluating interactive responsiveness, video playback, browsing, or file transfer. Write down the app or destination you will use. Do not use a generic speed result as a substitute for the task.
- Establish a baseline. Test the same device and access network without the VPN, if that is appropriate for your setup. Note latency and throughput to the chosen test endpoint. This helps distinguish a weak local connection from a route-specific issue.
- Check client routing. Confirm the VPN client is connected and that the test app is included in the intended routing mode. If you use rule-based routing, verify that the relevant app or domain matches the expected rule. Avoid running two proxy or VPN clients at once, since overlapping routes and DNS settings can complicate the results.
- Test one route at a time. Select IEPL, relay, or direct where these options are available, then wait for the connection to settle. Test the same endpoint and application. Repeat the sequence for the other routes without changing the access network or test conditions.
- Repeat at different times. Include both a quieter period and the evening period when you normally use the service. A route can be stable at one time and congested at another because of shared capacity, access-network load, or changes beyond the VPN provider’s network.
- Compare the pattern, not the best result. Look at whether latency, jitter, loss, throughput, and real application behavior are consistently acceptable. One unusually good or bad result is a reason to repeat the test, not enough evidence by itself to declare a route best.
When you save notes, keep the language precise. “The route had lower latency to this test server during this session” is more useful than “IEPL is faster.” If a route performs well for video but less well for a game, record both outcomes. They may use different destinations, protocols, and traffic patterns, so the difference does not automatically indicate a fault.
If all routes perform poorly, check the local network before changing VPN settings repeatedly. Restarting a router or switching between Wi-Fi and a wired connection can help isolate access-network issues, but change one variable at a time. If only one application fails, check its routing rule, DNS settings, and current service status rather than assuming the entire VPN connection is down.
- ✅ Keep the device, network, test endpoint, and client mode consistent.
- ✅ Compare several measurements and test the application you actually use.
- ✅ Repeat tests during the time window that matters to you.
- ❌ Do not treat a single speed-test screenshot as proof of sustained performance.
- ❌ Do not assume that a route name guarantees a private end-to-end path.
Choose a route by workload and time of day
For gaming and other interactive tasks, prioritize stable latency, low jitter, and minimal packet loss to the actual game or service region. Maximum download throughput is usually not the deciding factor once it is sufficient for the application. A route with an extra relay may still be preferable if it produces a steadier path to the destination; a direct route may be preferable if it avoids an unnecessary hop without introducing congestion. Test the game’s own network display when available, and remember that the route to a matchmaking service may differ from the route to the game server.
For video streaming, sustained download performance and continuity matter more than a brief peak. Test the selected route during the hours when you watch, and observe whether playback starts reliably and maintains the quality you need. If buffering occurs, distinguish between a route issue and local Wi-Fi interference, device load, or a problem at the streaming service. Changing exit regions can also affect which service endpoint you reach, so keep region and route changes separate while testing.
For everyday browsing, look at the combined experience: DNS response, connection establishment, page loading, and whether local sites still use the intended path. A route may have acceptable throughput but feel slow if name resolution or connection setup is delayed. Rule-based routing can help keep selected local traffic direct while sending other apps through a VPN, but rules need to match the traffic you intend to handle. Confirm behavior with the specific browser or app rather than assuming that a system-wide setting covers every program.
Evening congestion deserves its own consideration. During busy periods, demand on a home broadband connection, mobile network, transit link, or shared VPN capacity can change the result. A private segment can reduce exposure to some kinds of public transit congestion between its endpoints, but it cannot remove congestion on every surrounding network. Likewise, a relay can help only if its alternative path has suitable capacity and routing. Compare routes at the time you actually use them, not only when the network is quiet.
Finally, route performance is not a fixed property of a label. Providers can change network arrangements, destinations can alter their routing, and your access network can vary. Recheck the routes when your experience changes, but avoid chasing every short-lived fluctuation. Use a small, consistent set of tests and choose the route that gives you the most reliable experience for your workload.
