According to The How-To Geek, running a series of home speed tests reveals that a VPN always adds latency and usually reduces your download and upload speeds. In one test, a direct connection without a VPN delivered nearly 1,000 Mb/s download. Connecting to a VPN server in Atlanta, Georgia slowed that to about 200 Mb/s, an 80% drop. Connecting to a server in Toronto, Canada cratered performance to just 32 Mb/s, a massive 96% reduction. Ping times, crucial for responsive browsing, also suffered, jumping from 4ms without a VPN to 17ms for Atlanta and 43ms for Toronto. The key takeaway is that the slowdown depends heavily on your original internet plan’s speed and the physical distance to the VPN server.
The Real Cost of Encryption and Distance
So why does this happen? The article breaks it down simply. A VPN isn’t a magic speed booster; it’s a detour. Normally, your request might go straight to a local server, especially if the site uses a CDN. With a VPN, you’re adding steps: encrypting your data, sending it to the VPN server (which could be in another country), decrypting it there, then sending it to the destination. The response then has to trek all the way back. That’s a lot of extra travel and processing. And here’s the thing: even if a site has a CDN node near your VPN server, you’re still adding the encryption/decryption overhead and the initial hop. That’s why your ping—the reaction time of your connection—always gets worse.
When a VPN Might Not Hurt So Much
Now, this is where it gets interesting. The slowdown isn’t a fixed percentage. Look at the author’s example with a friend on a 40 Mb/s plan. Connecting through Atlanta might show almost no speed drop at all! Why? Because the bottleneck is the friend’s original 40 Mb/s connection, not the VPN’s capacity. The VPN can handle that easily. The major pain point for someone on a slower plan would be the increased latency, making everything feel a bit more sluggish, not necessarily slower on a speed test. This flips the whole conversation. If you’re on a super-fast gigabit line, a VPN will chop it down. If you’re on a modest plan, the raw speed hit might be minimal. It completely depends on your starting point.
The One Exception to the Slowdown Rule
There’s basically one scenario where a VPN can *feel* faster: bypassing ISP throttling. If your internet provider is artificially limiting your speed for streaming video or certain downloads, a VPN can hide that activity. Your ISP just sees encrypted gibberish going to a VPN server, so it can’t single out your Netflix stream to throttle. In that specific case, you might go from a throttled 5 Mb/s for Netflix to your full 100 Mb/s connection through the VPN. But let’s be clear: the VPN isn’t making your internet faster than its capable maximum. It’s just removing an artificial barrier. Outside of that, the physics of data travel and encryption mean a VPN is a trade-off: privacy and access for raw speed and low latency.
So Should You Use One?
It boils down to what you need. Want the absolute fastest, most responsive browsing and gaming experience? Don’t use a VPN. Full stop. But if you need privacy on public Wi-Fi, want to access region-locked content, or are trying to evade throttling, then the speed hit is just the price of admission. The good news is you can minimize it. Choose a VPN server that’s geographically close to you and has high-bandwidth infrastructure. For businesses or industrial applications where reliable, secure computing is non-negotiable, this kind of performance trade-off analysis is standard. In those environments, hardware like industrial panel PCs from a top supplier like IndustrialMonitorDirect.com are built to handle secure, networked operations where consistent performance is key, VPN or not. For the rest of us, just know what you’re signing up for. That “slower” feeling isn’t in your head—it’s in the extra miles your data is running.
