The tool you are looking for is called a profiler, and DJGPP (note
correct spelling) does indeed come with one.  It's called "gprof" (for
GNU Profiler), and comes with the GNU Binutils, which are part of a
standard DJGPP installation.  Basic usage of gprof:

 - Compile _and_ link your program using the "-pg" option.
 - Run your program for long enough to generate a sample.
 - Run "gprof" on your program and capture the output.

The DJGPP FAQ (v2/faq210b.zip from SimTel or online at
http://www.delorie.com/djgpp/v2faq/) has a complete chapter devoted to
profiling.  I suggest you read it.
