Perfping is a tool that allows you to ping a host continuously or with a single ping using different data volumes. This can give you an indication of the performance of the route to your host.You can change the ping intervall from 2 to 30 seconds using various timeouts. The timeout is always smaller than the pinging interval. Results are written to log window and log file if so chosen. Unreachable hosts have a value of 0 ms.
