With older programs like email and ordinary web browsers you may never notice your internet is less than rock stable, but with high jitter, video, VoIP, and games will once more start misbehaving. What this means for you is the more jitter you have, the less stable your connection is. Many things can cause jitter: interference, overburdened network hardware, or a bad connection. Your PC is sending out packets of information to websites and they're not getting there, or vice-versa. Sometimes jitter is so bad that packets are lost. So, for example, if you ping a site once and it takes 1ms to report back in and then the next ping packet takes 10ms to report in, you have a horrible case of jitter. Jitter, or more precisely packet delay variation, is a measurement of the times it takes for internet packets to arrive to your system. You may be losing packets or suffering from jitter. That's because ping, latency, and bandwidth only tell part of the story. your connection may still not be that good. Netflix currently uses 35.2 percent of all fixed internet traffic in North America, and most of that is in prime time.Įven with a low ping and fast bandwidth. Thus, while I can see great speeds in the morning and afternoon, when the evening comes around and everyone starts watching Netflix, my speed goes down. It's because cable internet's bandwidth is shared between users on the same cable segment. Is that because I'm some kind of network genius? Nope. Sometimes, however, I get 120 to 130Mbps. In the real world, ISPs usually over-promise and under-deliver on bandwidth. That's pretty good, but I pay for 100Mbps. You may notice that my results are from 60 to 70 Megabits per second (Mbps) down. Generally speaking, these tests will show you getting the fastest possible speeds. ISPs also have their own performance tests. All this test does is tell you how fast your downloads are. ![]() Netflix, which has reason to believe ISPs deliberately slow down its shows, has its own speed test: Fast. In practical terms, that means, for example, online action gaming and video-conferencing are almost impossible with either kind of internet connection. These technologies simply aren't capable of performing well. With some kinds of internet connections, notably dial-up and satellite, you will always see poor ping and latency performance. The simple Google Speed tests upload, download, and latency.
