I'm curious to know what the average execution time of a C program is.
Perhaps it can be estimated based on the size of its input file or its
output file?

In all seriousness, this can't feasibly be answered, since PostScript
is a full programming language.  However, I can give you some
"expectations".  Take a page with 3000 words of text, in 3-4 different
fonts, with two moderately complex bits of line art.  This page should
take approximately 2-10 seconds of interpretation time, if the program
is well-written, depending on the horsepower of the interpreter.  If
you're talking about an Apple LaserWriter Plus, 8-10 seconds is
probably reasonable, if you're using a LaserWriter II NTX, 4-6 seconds
is probably about right.

Anything more than this can be chalked up to the inefficiencies of the
driver.  The "average application" will probably take about 10-20
seconds on comparable printers to print a page like the one I've
described.
