Things I've learned..... Always predict worse than you actually think (15%) and include a caveat. 8)
This is not "prediction". What you describe is planning.

The original poster asked about predicting system performance (using automated tools).

There are hundreds of applications on the Internet named "Perform" ... To discuss a particular application, please post the link.

Thanks.

PREDICT-G1YYH(1)					      General Commands Manual						  PREDICT-G1YYH(1)

NAME
predict-g1yyh - satellite tracking program DESCRIPTION
The predict-g1yyh program is a variant on the predict satellite tracking program that includes patches from John Heaton, G1YYH, that add new functionality. This man page documents only the features that differ between predict and predict-g1yyh. See the predict man page for information on the features of the program that are not described here! The user may step forwards/backwards through the satellites in the Single-Sat display using the '+' and '-' keys, and may remove blank entries from the Selector page. MultiSat has been reformatted to display upcoming passes below the satellites in view. Using the 'i' and 'k' keys you can toggle between distances in Imperial or Kilometres. Using the 'l' and 'm' keys you can toggle between displaying the normal latitude/longitude or Maiden- head locators for the sub-satellite location. The SingleSat display allows use of the arrow keys to change the frequency up/down and to move to the next/previous satellite using left/right arrows. A new method of selecting satellites is implemented. Instead of pressing a character next to a satellite name, a scrolling menu is pro- vided. This means that the program is now capable of handling a much larget list of satellites, currently a maximum of 250. Finally, the height of the terminal window containing predict can be increased dynamically if you want to display more information than will fit on an 80x24 terminal window! SEE ALSO
