My code was merely an example of very simple loop. Its purpose was not 
to calculate something, but run through the loop, and execute 
multiplication on every iteration.

My main area of development is processing of rather large amounts of 
data (billions of entries, primarily processed by regular expressions, 
with some statistical analysis on top, and potentially - addition of NLP 
later). You _have_ to iterate through every entry of the incoming data 
(which might already be in the database, plain text file, or might be 
just a "fire hose" of data pouring into the system in real time).

While I'd LOVE to have a nice and clean syntax, performance is still 
number 1 on my list of priorities, therefore I asked if maybe there are 
ways to improve Ruby performance.
