A Slashdot User Asks…
Lower, steadier latency and ping times come from sending game and call traffic over more than one internet connection at once. Speedify is an app that combines two or more internet connections – Wi-Fi, Ethernet, and 4G/5G cellular – and its Redundant Mode sends data over every connection so the fastest copy wins.
Here is the real-world test showing how much Speedify cut ping times.
With Speedify, your internet stays on when one connection fails.
When one of your connections drops, Speedify automatically routes your traffic to your remaining connections — so calls don't cut out and downloads don't stall.
How do I use WiFi and 4G/5G cellular at the same time with Speedify?
Pick your two internet connections and your device below and we'll take you to the step-by-step setup guide.
A New Feature is Born
Redundant Mode has been available to all users running the latest version of Speedify for just over a week now, and already folks have been writing to tell us how awesome the new feature is.
But, I wanted to dig a little deeper and see what’s happening under-the-hood. The obvious question is whether or not such a system can really help improve ping times. If pings are essentially measures of the speed of light, then you might expect little difference in performance from sending duplicate packets in parallel.
The Control (without Speedify)
Let’s look at some real ping times from a pair of 4G wireless cards in our office, first without Speedify at all.
Verizon 4G MiFi
Ping statistics for 74.125.29.147:
Packets: Sent = 47, Received = 47, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 56ms, Maximum = 411ms, Average = 120ms
Clear 4G USB modem
Ping statistics for 74.125.29.105:
Packets: Sent = 45, Received = 45, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 68ms, Maximum = 388ms, Average = 125ms
While there is a clear minimum ping time, there isn’t really a limit on the maximum ping time. 4G cards have ping times around 50 ms when everything works well, but sometimes they randomly delay packets by hundreds of milliseconds!
Now, with Speedify in Redundant Mode
To improve on this, I connect to Speedify, select Redundant Mode, and run the pings again. In Redundant Mode, each ping is sent on both connections, and whichever one gets through first is the one delivered. Here’s what I get:
Clear 4G + MiFi 4G through Speedify Redundant Mode:
Ping statistics for 74.125.29.103:
Packets: Sent = 41, Received = 41, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 52ms, Maximum = 106ms, Average = 69ms
The average ping times of 125 ms and 120 ms by themselves, gets cut down to just 69 ms, almost twice as good. That’s a 40% improvement with Speedify in Redundant Mode.
In this case, Speedify’s Redundant Mode delivers because 4G networks suffer from jitter (variable latency). There are other scenarios where Speedify helps, too: packet loss, and of course, networks losing connectivity altogether.
So next time you’re gearing up Battlefield, or maybe trading stocks on the Internet, try taking Speedify for a spin.
