Guidelines for Optimizing

size of the program
|
As the program increases
in size, the potential for savings increases. Focus on improving the
efficiency of large programs.
|
number of times the
program runs
|
The difference in resources
used by an inefficient program and an efficient program that is run
once or a few times is relatively small, whereas the cumulative difference
for a program that is run frequently is large. Focus on improving
the efficiency of programs that are run many times.

volume of data
|
As the volume of data
increases, the potential for savings also increases. Focus on improving
the efficiency of programs that use large data sets or many data sets.
|
type of data
|
Specific efficiency
techniques might work better with some types of data (for example,
data that has missing values) than with others.
