Why Is My Internet Slower With a VPN?
Some performance loss with a VPN is normal because traffic is encrypted and takes an additional route. The size of the slowdown depends on the server, protocol, device, network and current congestion.
The short answer
Some slowdown is normal because a VPN encrypts your traffic and sends it on a longer route through the VPN server. With a nearby, lightly loaded server and a modern protocol, the difference is often small enough not to notice in everyday use. A large slowdown usually points to a distant or busy server, an older protocol, or a device that struggles with encryption.
Where the slowdown comes from
| Cause | What you notice | What helps |
|---|---|---|
| Distance to the server | Higher latency; pages feel slow to start | Pick a server closer to you |
| A busy server | Speeds vary through the day | Try another server in the same city or region |
| Protocol choice | Lower throughput on some devices | Try WireGuard or the app's equivalent modern option |
| Device processing power | Slow on older phones, laptops and routers | Run the VPN on the device, not an underpowered router |
| Weak Wi-Fi | Slow with or without the VPN | Test closer to the router or on a wired connection |
How to measure the difference fairly
- Use the same device, browser and network for every test, ideally wired Ethernet or close to the router.
- Pause large downloads, cloud backups and streaming on the network.
- With the VPN off, run a reputable speed test three times and note the typical result. Cloudflare's test at speed.cloudflare.com also reports latency under load.
- Connect to the VPN server you actually plan to use and repeat the three tests.
- Compare typical results, not the single best run. Look at latency as well as download speed.
Latency matters most for calls, games and how quickly pages begin to load. Download speed matters most for large files and video quality. A big download number alone does not mean a video call will work well.
Fixes in order of impact
- Choose a nearer server. This is usually the single biggest improvement.
- Switch protocol. WireGuard-based options are often faster than older protocols on the same hardware.
- Try another server in the same location if one is overloaded.
- Use split tunnelling for heavy, non-sensitive traffic, such as game downloads, so it skips the VPN.
- Update the VPN app and the device's operating system.
- Move the VPN off an old router and onto the device itself, if your router is the bottleneck.
Signs the VPN is not the problem
If speeds are just as slow with the VPN disconnected, look at your Wi-Fi signal, other devices using the connection, or your plan's speed. If only one website or service is slow through the VPN, that service may be limiting traffic from VPN addresses. Excluding it with split tunnelling is a reasonable fix.
Can a VPN ever make things faster?
Occasionally, if a network deliberately slows a particular kind of traffic or routes it poorly, a VPN can avoid that path and improve speed. This is the exception rather than the rule, so treat claims that a VPN will "boost" your internet with caution. Test it on your own connection before relying on it.
