Finding a Reliable Online VPN Speed Test

looking for a tool to test bandwidth between vpn sites
The distance between your computer and the server directly affects speed, as in most cases your connection has to be routed through several hubs in order to make long-distance connections. Pick and choose a few culprits then pause or close them entirely to ensure you have accurate results. Before running a test on Speed. OS Security From novice to tech pro — start learning today. Many VPN provider offer tools for you to use to get a rough idea of how fast connecting to each and every VPN server will be, but using these alongside a speed testing service like Speedtest. The VPN test will automatically choose this location, but the non-VPN test won't, skewing the results before comparison.

The VPN speed test is available for all major devices StrongVPN supports, including:

How to Test VPN Speed

I suppose you could call me a network engineer if you base my talents off of some past network engineers I've worked with which is kinda sad really. Since then either my VPN experience has been limited to using OpenVPN on my own personal stuff, or relying on other dedicated network engineer s to manage it.

I conferred with a colleague on this and his experience was similar - he expects site to site VPN performance to about match that of Internet site to site performance when no fancy WAN Opt is in use. It's possible the performance could be even higher, I noticed that speed continued to increase the longer the transfer was running.

Keep in mind that bandwidth does not matter at this point since latency dictates the round-trip-time. I don't know what sort of calculation was done, but the throughput matches what I see on the raw Internet. These are all single threaded transfers.

In all cases the files being copied a re highly compressed in my main test case the MB file uncompresses to 14GB , and in the case of the SCP test the data stream is encrypted as well. I've done multiple tests over several weeks and the data is consistent.

I opened a support ticket to try to get support to explain to me what more was going on but they couldn't answer the question. They said because there is no hops in the VPN it's faster. There may be no hops but there's still 95ms of latency between the systems even within the VPN.

I mean just a few years ago I wrote a fancy distributed multi threaded file replication system for a company I was at to try to get around the limits of throughput between our regional sites because of the latency. I could of saved myself a bunch of work had we known at the time and we had a dedicated network engineer at the time that this sort of performance was possible without really high end gear or specialized protocols I was using rsync over HPN-SSH.

I remember trying to setup OpenVPN between two sites at the company at that company for a while to test throughput there, and performance was really terrible much worse than the existing Cisco VPN that we had on the same connection. For a while we had Cisco PIX or ASAs I don't recall which but had a Mbit limit on throughput, we tapped them out pretty quickly and had to move on to something faster.

I tested another VPN link between a pair of Cisco firewalls and their performance was the same as the raw Internet 15ms of latency between the two , I think the link was saturated in those tests not my link so I couldn't check it directly at the time. The only special feature licensed is high availability, other than that it's a basic pair of units on each end of the connection.

So I researched a few other players and met with Sonic Wall about a year ago and was satisfied with their pitch and verified some of their claims with some other folks, and settled on them. So far it's been a good experience, very easy to manage, and I'm still just shocked by this throughput. As the next step, we will calculate the percentage of base speed when not using a VPN for all the good servers that we have identified.

This will give us an estimate of drop in speeds for various servers. We will then repeat this test four times in a day to get some reliable data that is normalized to represent a more accurate picture. This series of steps and tests will finally help us identify fast servers for any VPN service and give an overall speed rating for the VPN's network.

These steps constitute the most stable VPN speed test methodology we could devise. We will update this guide if we find a better way to test VPN speeds. We would also love to hear your suggestions on improving these tests further.

Leave a comments if you have ideas to enhance our tests in any way. I take a deep interest in finding out why things work the way they work. I also write about VPN services, anonymity tools, and privacy tools here at Dealarious. Me , which is an HTML5-based speed test. Me calculates download speed? Compute a Median of Medians Once we have the median speeds for all servers, we will take another median of all these median speeds.

Besides, it will help us filter out slow VPN servers and identify good servers. We will only consider servers that rank higher than the median of medians.

Once you have a control number, connect to the VPN and perform the test again using the same location. Once you've finished testing, you should have some results to compare.

Generally, the VPN results will be slightly lower than the control speed results. This is normal, the result of the tunneling and compression mechanisms VPNs use to secure data transmitted over the network. For the best reflection of available connection speed, you should perform your tests when as few people are using your LAN and VPN connections as possible, to reduce bandwidth congestion. Performing multiple tests for each value and averaging the results can also be useful for determining your overall connection speed.

There are several factors that can lead to slower connection speeds on your VPN. Network congestion caused by other users on your LAN or wireless connection will slow down overall speed, which will in turn slow down your VPN speed. Also, if there is considerable distance between you and your VPN's host, especially transcontinental distances, then performance will always be less than you can expect from a closer connection.
