IFTOP shows a real time updated list of network connections based on their network usage ordered on every 2, 10 and 40 seconds average.
If you’re having network throughput issues, you can work through a series of quick troubleshooting measures based on how you’ve isolated the problem.IFTOP is a real time network bandwidth monitoring tool through Command line.
Several ISPs feature speed tests, but they almost all license their technology from Ookla. Many sites offer web-based throughput testing, including Ookla’s Speedtest, Fast from Netflix (which has an interest in helping you figure out if you can’t stream effectively), and Google and Measurement Lab (in support of Google Stadia). Macworld contributor Jason Snell created a way to see output from networkQuality in your menu bar with a third-party utility that lets you add items. If your network or Internet connection has a lot of hiccups and dropped packets, RPM offers better insight than a latency snapshot. Thus latency may show you the round-trip speed average over a few seconds and RPM provides a total number of data round-trips performed one after another over a minute.
Measuring RPM requires a longer test than that typically used for latency. RPM is another way to think about latency, as it’s the sequential number of operations that can be performed per minute. Such tools include Speedtest and the macOS Monterey command-line tool networkQuality. However, to measure how much throughput you have to and from the internet-the actual real performance of your connection-you have to use a testing tool that interacts with a server somewhere else and then reports on the speed of those interactions. Some routers and broadband modems let you log in and view throughput data or run different network tests. You can also pick up some information about your network connection in the system Wi-Fi menu. Peak Hour has the unique ability to also sample bandwidth data from routers and broadband modems that broadcast the information (more on that in a bit). This includes macOS’s Activity Monitor (in Applications > Utilities), Peak Hour, and iStat Menus. This includes all data traveling within your local network and that being sent to and received from the internet. Many network tools measure (a single snapshot) or monitor (ongoing samples) data going in and out of a single computer.
