I think there might be languages that are better suited for this kind of 
tasks, especially if the text becomes _really_ long. Anyway, it is 
fairly easy in Mathematica and resonable fast, too:

text = Import["ExampleData/USConstitution.txt"];
words = StringCases[text, WordCharacter ..];
Tally[words]
