So, I'm trying to use streams more and better understand how to use them 
properly.

There was this little contest over at Treehouse to write an app that would 
count the words in a text file after being filtered from a certain set of 
words in another file.

Myself and one other person chose to write our apps in node.

I wrote mine using streams and they wrote theirs without. I have used the 
time command to compare the two. Mine is consistently about 5 times slower.

Link to mine: https://gist.github.com/DanSchmidt/10000777
Link to their's: https://gist.github.com/pleary/9967501#file-waldo-js

I could understand if some of my transform and filtering logic was perhaps 
less performant than another's, but 5 times slower seems to suggest I'm 
probably doing something wrong with the streams.

Any help would be appreciated, thanks.
