Nir Softer has announced the availability of NetworkLatencyView, a handy network monitoring tool and the latest program to join the NirSoft lineup.
The program detects new TCP connections on your PC, calculating and displaying their network latency. As Sofer points out, “the latency value calculated by NetworkLatencyView is very similar to the result you get from pinging to the same IP address.”
Any captured data is displayed in a familiar NirSoft-style table. Each connection gets a single line, with columns detailing its source and destination addresses and host names, along with a list of up to ten latency values, and the current average.
Any of these fields can freely be sorted by clicking on the column header, making it easy to (for example) pick out the slowest connections.
You can start or stop data capture with a click, and there’s an option to save your latency figures as a report, perhaps useful if you want to see how they change over time.
As is often the case with this kind of network tool, you’ll get the most reliable results if you install a dedicated capture tool first (NetworkLatencyView works with WinPcap and Microsoft’s Network Monitor Driver).
If you’d prefer to keep things simple, though, you can just choose the “Raw Sockets” option. The figures you’ll see may not be quite as accurate (and sometimes you may not see any figures at all), but when we tried this on a test Windows 8 PC NetworkLatencyView was able to provide reasonable figures without the hassle of installing any further software.
