Performance
Measure latency, response time and path quality to any destination, with nothing to install.
What it is and what it is for
Latency and response time say more about connection quality than the speed printed in a contract. These tools measure the path to a destination without installing anything on your device.
When to use it and which problems it solves
Use them when a site feels slow, when comparing your network with another one, to confirm a port is answering, and before filing a well-founded complaint with your provider.
