Why a VPN Slows Down Internet Speed, 5 Fixes, and How Speedify Makes Up for It with a Second Connection

Speedify Bonding VPN Revives Your Internet Speed

Yes, a typical VPN does slow down your internet. Everything you send is encrypted and then pushed through a single internet connection to a server that may sit thousands of miles away, and both of those steps cost time.

Speedify, an app that encrypts your traffic like a VPN, can make up for that loss. Speedify uses Wi-Fi, 4G/5G cellular, Ethernet, Starlink and satellite internet connections at the same time and adds their speeds together instead of pushing everything down one internet connection. That gain needs two or more internet connections; on a single connection Speedify works as an encrypted VPN and can be a little slower, like any VPN.

You will find the five main reasons a VPN drags, five fixes to try, and what changes for streaming, video calls and remote work once Speedify is the VPN you use.

Top 5 Reasons Why a VPN Slows Down Internet

1. Server Distance and Location
One of the primary culprits why a VPN slows down internet is connecting to servers that are geographically distant from your location. When your data travels thousands of miles to reach a VPN server, latency increases dramatically. The further the server, the longer it takes for your requests to be processed and returned, resulting in noticeable slowdowns.

2. Server Overcrowding
Popular VPN servers often become overcrowded, especially during peak usage hours. When too many users connect to the same server simultaneously, bandwidth gets divided among all users and speeds drop sharply. This is particularly common with free VPN services that have limited server infrastructure.

3. Internet Service Provider (ISP) Throttling
Some ISPs intentionally slow down VPN traffic through a practice called throttling. They can detect VPN usage patterns and deliberately reduce bandwidth allocation for encrypted traffic. This anti-VPN stance by certain ISPs can severely impact your connection speed.

4. Outdated VPN Protocols
Using older, less efficient VPN protocols can slow down your connection. Legacy protocols like PPTP or older versions of OpenVPN may not utilize modern encryption standards efficiently, creating unnecessary overhead that impacts performance.

5. Device and Network Limitations
Your device’s processing power, available RAM, and network adapter capabilities directly affect VPN performance. Older devices may struggle to handle modern encryption protocols, while network congestion on your local connection can create bottlenecks that slow down your VPN tunnel.

VPN Speed on an iPhone and in Online Games

On an iPhone, a VPN slows your internet for the same reasons: encryption and a longer route to the server. Speedify on an iPhone (iOS 17 or later) can use Wi-Fi and 4G/5G cellular at the same time, so the second connection makes up for that loss when the Wi-Fi is weak or busy.

In online games, any VPN adds a little ping, because your traffic goes through a server first. With two connections in Redundant Mode, Speedify sends each packet over both and uses the copy that arrives first, so your ping follows the faster connection; Speedify also keeps the game connected when one connection drops and moves traffic away from a connection that is losing packets.

5 Troubleshooting Steps to Fix Internet Slow Downs Due to VPN Usage

Before you toss your device out the window, try these proven fixes:

1. Switch to a Closer Server
Start by connecting to a VPN server that’s geographically closer to your location. Most quality VPN providers offer servers in multiple countries and cities. Choose one within your region or neighboring countries to minimize latency and improve connection speeds.

2. Restart Your Router and Devices
A simple reboot can clear network congestion, close background processes hogging bandwidth, and refresh your connection.

3. Try Different VPN Protocols
Experiment with various VPN protocols available in your client. Modern protocols like WireGuard or IKEv2 often provide better performance than older options. Many VPN services now offer automatic protocol selection that optimizes for speed and security.

4. Change Server Locations During Peak Hours
If speeds drop during busy evening hours, try another server near you; a less crowded server in the same region often helps.

5. Test Your Internet Speed without the VPN
Run speed tests with your VPN disconnected to establish a baseline. If your regular internet speed is already slow, the VPN will only amplify the issue. Contact your ISP if your base connection is underperforming.

BONUS: Use a VPN with Speed Optimization Features

Some VPNs are built for speed, combining multiple connections, avoiding congestion, and actively managing packet loss. That’s where Speedify comes in.

How Speedify Makes Up for VPN Slowdown with a Second Internet Connection

When the usual fixes fall short, Speedify takes a different approach. Conventional VPN services connect to the server through a single internet connection. Speedify connects to the server through every internet connection you have at once and splits your traffic across them.

All your traffic still leaves from the same Speedify server, so your public IP address stays the same when one connection drops, and video calls, streams and logged-in sessions carry on.

How Speedify Makes Your Internet Faster

Here’s how Speedify makes up for VPN slowdown and, with two or more connections, can make your internet faster and more reliable:

  • Multi-Connection Support: Speedify uses all available connections at once, splitting traffic across them for more combined bandwidth.
  • Failover Protection: If one connection drops or slows down, Speedify moves your traffic to the others (Speedify says failover happens in milliseconds), so calls and streams keep going.
  • Smart Encryption: Speedify protects your traffic with DTLS 1.2 and AES-256-GCM or ChaCha20-Poly1305 encryption.
  • Real-Time Optimization: Speedify detects packet loss, jitter and congestion on each connection and shifts traffic away from the weaker one.
  • Global Server Infrastructure: Speedify’s server network covers more than 50 locations on paid plans, so you can usually connect to a server near you.

With two or more internet connections, Speedify gives you privacy and speed together. You can try Speedify on the free tier, 5 GB per month with a free account.
