Performance Pinging, Perfping.exe Version 1.2.1; December 2004 Software by Carsten Schmidt If you like this software, please consider donating. Follow the link: http://software.ccschmidt.de Please report bugs and feature requests to: Carsten@CCSchmidt.de How does it work and what does it do? 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 interval 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. The analysis function sends various pings, 10 each of 10 bytes, 100 bytes, 500 bytes, 1 kbytes, 10 kbytes, 50 kybytes and 64 kbytes. The round trip times are shown with the total and average times. Comments: - Errors are written to file and log window but may be shown later than successfull pings when changing ping intervall and timeout during runtime - Thanks to François Piette for the internet component suite, Angus Robertson for the threaded version of Ping and Dr. Jürgen Kehrel for the graph component.
