How does it work and what does it do?
Perfping
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 kbytes and 64 kbytes. The round trip times are
shown with the total and average times.

Perfcopy
You may test network performance by copying files to UNC locactions. Simply select
a UNC location (e.g. \\10.0.0.1\c$\temp\) and a file size. Then just copy once or 
start the timer.


Comments:
- Errors are written to file and log window but may be shown later than 
  successfull pings when changing ping interval 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.
- For the perfcopy function, write and delete permissions are needed on the target 
  share. 
- Please note: the smaller the copied file, the shorter is the time interval needed 
  for copying. This also means that the result is more imprecise. I suggest you use 
  the biggest file your network can handle. In any LAN, you should use nothing smaller 
  than 1 MByte, only over slow WAN links you should use the 100 KByte file.
  

Future development
- thread the perfcopy function
- drop down list for UNC targets
- add tray icon to show status
- add threshold alarms
