The jitter value should be below 30ms and is generally below 10ms. The higher the jitter value, the more likely a packet loss will occur. In other words, if every packet takes the exact amount of time - no matter how long - to arrive at the destination, then there’s no jitter. Jitter, often called Packet Delay Variation (PDV) or ping variations, measures ping values over time - the entire test. Generally, a ping of 15ms or shorter is considered excellent. The shorter your ping is, the better your Internet connection is for applications that require real-time interaction, such as Wi-Fi calling or online gaming. It’s the amount of time, shown in milliseconds, needed for a data packet from one party to reach another or vice versa. Ping is the fixed latency or lag at a given time - in a speed test, it’s generally measured at the beginning. Lag (or latency): Ping vs jitterīoth ping and jitter relate to the delay in a connection, but they are slightly different. Packet loss shouldn’t be higher than 1 percent. Most of the time, this is the consequence of a bad physical connection or incompatible MTU settings. ) Packet lossĪs the name suggests, packet loss happens when a packet of data is either not received or partially received. In this case, you might need to conserve your Internet bandwidth. Don’t use them if you have a modest broadband connection. ( Note: Cloud-recording security cameras, like those from Google or Arlo, and “smart devices” in general, can put a massive strain on the upload.

Still, if somebody is seeding a torrent file, or uploading something large, without limiting the upload speed for the task, others might not be able to download anything.

But you might get the same rate for both directions with a more modern connection, like a fiberoptic service. In most traditional broadband connections, such as one via a cable modem, the download speed tends to be much faster than the upload speed. That said, when the upload pipe is all clogged up, you can’t download anything at all. That’s because your computer uses the upload pipe to send a confirmation to the remote server that it has received a packet and is ready for the next one. While we use more of the download pipe, data transmission - delivered in small portions called packets - needs both directions to work. Things like sending an email, posting a photo or comment to Facebook, saving a file to Google Drive, using cloud-recording/smart devices, etc., use the upload pipe. Upload represents the speed of the opposite direction. (In a speed test, download is the speed from the remote server that hosts the test data to your device.) That said, streaming a movie, surfing a website, downloading a file, getting an email, etc., use the download pipe. Internet speed: Upload vs downloadĭownload speed represents how fast you can pull things from outside your local network. And you might also see a few other values, including ping, jitter, and package loss.įollowing is the breakdown of what they mean. When testing an Internet connection, you’ll get two main numbers, download and upload - sometimes they are called downlink and uplink. But there’s more than the download speed when it comes to the Internet. So yes, again, faster Internet is always better. Some of these applications - such as automatic updates - even occur within a connected device without you getting involved. If you have more than one person streaming simultaneously, you generally need to multiply those numbers with the concurrent clients to figure out the necessary real-time bandwidth.Īlso, there are a lot more online applications than streaming. Keep in mind that this is the speed required by a single stream. Take video streaming - one of the most bandwidth-taxing online activities - for example you’ll generally need a minimum download speed of: Faster is always better, but most importantly, you need certain speed grades to do specific tasks. It’s generally helpful to know how fast your Internet is. Why you should care about your Internet speed
