  I recommend a few trivial changes to the routines that evaluate CTEQ parton
distribution functions. These changes allow modern compilers to optimize the
evaluation routines, while having no quantitative effect on the results.
Computation time is reduced by a factor of 2 in matrix-element calculations,
and by 1.3-1.5 in the showering Monte Carlo event generators with fast detector
effects included. The results suggest that additional time should be invested
in optimizing these routines.
