If your unix is Linux running on PIII(maybe PII and Pentium too),
you can turn on the performance monitoring registers.
And one of the monitoring code is for number of
floating instructions executed.

find the keyword "profile", you will some compile options.
And there are some tools to interprete the profiling results.
for example: SGI profiling tool (perfex, ssrun)
