Abstract
A few changes to the routines that calculate CTEQ parton distribution functions allow modern compilers to optimize the evaluations, while having no quantitative effect on the results. Overall computation time is reduced by a factor of 4-5 in matrix-element calculations, and by 1.3-2.5 in showering Monte Carlo event generators. Similar improvements in performance may be expected in any calculations relying heavily on interpolation or multiple calls to functions.
