Does a VPN that doesn't drop speed due to distance exist? (Updated)

High latency can reduce the total data transfer rates but that has been largely fixed with the newer OS implementing what is called tcp sliding window. This is a extremely technical topic and it greatly depends on the application.

If you can get 150ms to the east coast from turkey that is going to be about the best you can possibly hope for. This is a speed of light thing. If you calculate the actual distance allowing for the fact the data has to go all the way there and all the way back you can see what the best possible number is. You of course never get that because of all the equipment in the path and even the parts that are fiber do not go directly because of mountains or deep ocean.

You next problem is you are to a point thinking about vpn incorrectly. In most cases what you are doing is just using your own internet connection. Lets say there is a vpn data center in new york and the server is also in new york. Then to make things simpler lets say your ISP, the VPN ISP and the server ISP are all the same. So if you go directly to the server your traffic goes from your house over the ISP path whatever that is, to new york. Now if you go to the VPN your traffic will likely follow exactly the same path to new york this time going to the VPN instead of the server. It would then come out of the vpn data center with a new ip and go to the server. Pretty much all you did would be the same as if you added another router in your house...except you would be using private ip addresses.

There really is no magic way to fix this. If you main goal is performance then you want to connect to a data center close to you or maybe in europe. You are hoping that the VPN provider is using a ISP that has better connectivity than your ISP to the server you want. This is massively complex to figure out since many server have multiple ISP and so do VPN providers.

Now there are some so called gaming VPN companies that work differently. These you access their network via a local node, pass over their connection between their data centers and exit in a remote country. Because they can buy guaranteed latency connection between their data centers rather than just use the internet they can do this. Unfortunately the VPN vendors are loaded with scammers that tell all kinds of lies. Finding a vpn provider in the piles of trash is very hard. Pretty much though you get what you pay for, this type of VPN is much more expensive because you are using dedicated data paths rather than just using the normal internet with a different IP.
