Evaluate network card performance under pressure.
Evaluate network card performance under pressure.
They seem to be some online stress tests for the internet, such as the one at speedcheck.org/nl.
Are you using Linux? Do you have another server close by that shares the same network interface, and would you like to connect them directly? Otherwise, if you need to rely on the network, your performance will depend on the speed of that connection and the equipment along the way.
This approach is unlikely to succeed because the network stack would recognize it as the same device and skip the physical network entirely. Even if it works technically, I believe you need a more realistic setup to test its effectiveness in practice. Since you're only running tests between two different machines, you'll need detailed statistics to identify which side caused the issue.
