If you want to speed up VPN performance, do not start by blaming the VPN service. Most slow VPN sessions come down to distant servers, the wrong protocol, weak Wi-Fi, background bandwidth use, or no baseline speed test at all. The first step is to identify what is actually slowing you down.［1］［2］［3］

If the networking terms in this article feel abstract, the complete VPN guide explains the tunnel, exit IP, and encryption model before you troubleshoot this specific case.

Here is the short version: test your baseline, switch to a nearby server, try another protocol, then troubleshoot your local network. That order is usually more useful than reinstalling the app.

Key Takeaways

A VPN adds some overhead, but real-world speed usually depends on the server, protocol, and local network, not just whether the VPN is on.［3］

Before you try to speed up VPN performance, test your connection without the VPN.［1］

A nearby server, the right protocol, and stable Ethernet or high-quality Wi-Fi are usually the biggest wins.

For streaming, calls, or gaming, look at download speed, upload speed, and latency, not just Mbps.［1］［2］

Many “slow VPN” problems are really unstable local network problems.

Before You Speed Up VPN Performance, Check Whether the VPN Is Really the Problem

The most useful lesson from Surfshark’s approach is simple: do not blame the VPN first. A cleaner test is:

Disconnect the VPN and run a baseline test;
Connect the VPN and test again with the same tool;
Compare download speed, upload speed, and latency.［1］

If you need a testing template, use How to Run a VPN Speed Test: 3 Steps to Compare Download, Upload, and Latency.

Netflix recommends about 3 Mbps for HD, 5 Mbps for 1080p, and 15 Mbps for 4K.［1］ That means “slow” depends on what you are trying to do.

1. Switch to a Closer Server

This is the most common quick win. The farther the VPN server is, the longer your traffic has to travel, and latency usually rises. If you only need encryption on public Wi-Fi or want to hide your real IP address, you usually do not need a server on the other side of the world.

Try this:

Choose the nearest country or region first;
Test 2 or 3 servers in the same region;
Test once during peak hours and once outside peak hours.

2. Change the VPN Protocol

Different protocols can produce very different speed results. WireGuard’s own page notes that older benchmarks are dated, but it still describes WireGuard and IPsec as usually faster than OpenVPN, with WireGuard retaining advantages in some scenarios.［3］

A practical order is:

Test the default protocol first;
Switch to a modern WireGuard-style protocol;
If your network is unusual, try OpenVPN or IKEv2.

If you want the protocol context first, read VPN Protocols Compared: WireGuard vs OpenVPN vs IKEv2.

3. Avoid Wi-Fi Interference, and Use Ethernet When You Can

Sometimes the VPN is not the slow part. The Wi-Fi is. Wireless networks are easily affected by walls, other devices, router load, and crowded channels. Once you add VPN encryption, existing weaknesses become more visible.

For a cleaner test:

Use Ethernet on desktops and laptops when possible;
Keep the router in an open position;
Avoid speed testing at the edge of Wi-Fi coverage;
Try 5GHz or Wi-Fi 6/6E if your router supports it.

4. Close Background Bandwidth Hogs

Cloud sync, system updates, game downloads, and NAS backups can all make a VPN look slow. Before testing, check that there are no automatic downloads, no large file sync jobs, and no other devices consuming most of the connection.

It sounds basic, but it often beats changing advanced settings.

5. Do Not Test Once: Run 3 Tests and Use the Median

Networks fluctuate. A single test can turn one random spike into a false diagnosis. Run 3 tests on the same server, record download, upload, and latency, then use the median result rather than the highest result.

6. Check Whether Your ISP or Plan Is the Limit

If your connection is slow even without the VPN, the VPN is probably not the root cause. Common issues include a low-tier internet plan, evening congestion, ISP throttling, unstable routing, or an old router. In other words, the VPN may simply expose a weak network that was already there.

7. Update the Client, System, and Network Drivers

Old VPN clients, operating system network bugs, and driver problems can cause connection failures, protocol fallback, unstable throughput, or poor speeds after sleep and wake.

8. Redefine “Fast Enough” Instead of Chasing Peak Download Speed

Different tasks need different speed metrics:

Use case	What matters most
Video streaming	Download speed［2］
Video calls	Upload and stability
Gaming	Latency
Remote desktop	Latency and jitter

If your download speed still says 200 Mbps but latency has doubled, meetings and games can still feel bad.

The Best VPN Speed-Up Order for 2026

Use this sequence:

Disconnect the VPN and test your baseline;
Connect to the nearest server and test again;
Try another server in the same region;
Change the protocol and retest;
Use Ethernet or improve Wi-Fi;
Close background tasks;
Retest outside evening peak hours;
If nothing helps, consider changing services.

Why can a VPN feel slower abroad?

Distance is only one part of the problem. A hotel, airport, train, or airplane network may already have high latency or limited capacity, and the route from that network to a VPN server can add another long segment. Test the base connection first, then compare a nearby server with the location you need for a service. If the nearby server is much faster, the bottleneck is probably distance or routing rather than the VPN app itself.

For a travel-specific test, use the same device and network while you try one nearby location, one required-region location, and a second protocol if the client offers it. Change one variable at a time and record latency, not just download speed. On airplane Wi-Fi, a VPN cannot create more cabin bandwidth; it can only add the protection layer you need for the available connection.

The server-location guide for travelers covers the location decision. For the special constraints of an aircraft connection, see VPN on airplane Wi-Fi.

Summary

To speed up VPN performance, follow a diagnosis order instead of chasing mystery settings.［1］［3］
Nearby servers, suitable protocols, and a stable local network usually matter most.
Judge speed by use case, not just peak download numbers.［2］
If the connection is slow without the VPN, stop blaming the VPN.

FAQ

Does a VPN always slow down internet speed?

It adds some overhead, but the drop is not always noticeable. Server distance, protocol choice, and local network quality usually matter more.

What are the first two things to try for better VPN speed?

Switch to the nearest server and change the protocol. Those two steps are the most likely to help immediately.

Why does my speed test look fine, but games still lag?

Games depend heavily on latency and jitter, not just download speed.

Should I reinstall the VPN app when it is slow?

Usually no. Test your baseline, switch servers, change protocols, then check your local network.

Can Wi-Fi noticeably slow down a VPN?

Yes. Wi-Fi interference and instability often become more obvious once VPN encryption is added.

Is WireGuard always faster than other protocols?

It is faster in many scenarios, but not every one. You still need to test on your own network.［3］
