To simulate an additional latency of 80 ms, just type sudo tc qdisc add dev eth0 root netem delay 80ms NetEm (already enabled in the Linux kernel) provides Network Emulation functionality for testing protocols by emulating the properties of wide area networks.

Sudo adduser iperf -disabled-login -gecos iperf Systemd script to start 41 iPerf3 server (port 9200 to port 9240). IPerf3 not allow multiple tests to a server => it is necessary to start several iPerf processes for not having the message iperf3: error - the server is busy running a test. To add / remove a public iPerf3 server, please report them to to host a iPerf3 server with Linux (Ubuntu / Debian) If a test is in progress, the following message is displayed: 'iperf3: error - the server is busy running a test. Multiple tests at the same time is not supported. IPerf3 servers will only allow one iPerf connection at a time.

That said, you will start to notice high ping if you're trying to make split-second decisions in an online multiplayer game, and it can also cause annoying delays during video call conversations. In most cases, ping differences are pretty minor, enough so that you won't notice them without running a speed test. Your ping might also rise slightly if you're connecting through something like a mesh router or a range extender, where your data needs to make multiple wireless jumps before reaching the modem. Ping will go up if you're connecting to a server that's very far away, or if there's some sort of interference somewhere in the connection. Think of it like a round-trip flight time for your internet connection. Simply put, the ping number is the time that it took for your device to send a signal to whatever distant server you connected to during the speed test, and then receive a response.

In addition to showing you the current upload and download speeds for whatever device you're running the test on, most internet speed tests will also give you a figure called ping, which is a latency measurement measured in milliseconds. It contains one 100 MB file and a small PHP file. That's not surprising, but it might make a slight impact on your results depending on the strength of your connection at the time of the test. To get started download the file here, unzip it then upload it to your server. You can even run the Ookla speed test on an Apple TV.Īll of that said, Ookla does display banner ads while you run basic speed tests. In addition to the website and the smartphone apps, Ookla also has apps that you can run on Windows or on Mac. Most recently, the service released a video-specific speed test that measures your network's ability to handle 4K video streams. Ookla's done a good job of keeping up with the times by adding new features and capabilities over the years. Incidentally, Ookla's speed test is also the one we use when we're testing Wi-Fi routers.

Popularity aside, we like Ookla for having everything a basic user needs from a speed test: accuracy, the ability to view your speed test history (when you create an account), a wide array of servers to connect to, and even a handy app for speed testing from your Android or iOS device.

One of our favorites is the Ookla speed test, which has a strong reputation for consistency and for being one of the first speed tests on the web.
