Ok, well then check this :
Linking by ordinal only gives a 2%-4% improvement. rebinding and
rebasing gives up to 18%.
So linking by ordinal only will help you a little. rebinding and
rebasing your .dll's will help much much more.
And infact, rebasing and rebinding makes the INT obsolete - because the
IAT is precalculated, so you can't get 22% by linking by ordinal and
rebinding and rebasing.
