scala-word-counter

A word counter example. Testing imperative programming vs functional programming performance.

The object LineWordCounterWorker has two methods:

1. countWordsFP: Counts the words in parameter passed filename with functional methods.
2. countWords: Counts the words in parameter passed filename in the traditional way.

In resources folder there are two files to test.

Some statistics I found:

Statistics (news2.txt , 77 KB , 612 lines)

Non FP (with countWords strategy) decision: 117 every: 90 willpower: 90 going: 81 goals: 81 write: 72 Elapsed time: 667 ms

FP (with countWordsFP strategy) decision: 117 every: 90 willpower: 90 going: 81 goals: 81 write: 72 Elapsed time: 359 ms

This is 85,7% better performance the Functional way!
