For programs that display a lot of text, consider redirecting text that is usually displayed on stdout to a file. Displaying a lot of text will slow down execution; scrolling text in a terminal window on a workstation can cause an I/O bottleneck (increased elapsed time) and use more CPU time.
The following commands show how to run the program more efficiently by redirecting output to a file and then displaying the program output:
myprog > results.lis
more results.lis
