But in the aplications where vector and matrix libraries are used, this
isn't always true. Sometimes, you need to do a simulation once or twice,
because tomorrow's fastest machine and tomorrow's theories will call for
a whole new simulation with different simplifications. But every 5% you
shave off means a day or two in time saved each time it runs. 

No worries about maintainability, you already have the fastest machine/
your budgets gone for this year (with man power is already payed for), but
it would be nice not to have everything waiting on the program to finish.
