I think the most interesting thing from that talk is when you 
said that Facebook's back end code is spending 15% of its time 
converting ints to strings.

I know you are looking at these small functions as simple 
examples of the optimisation tips you are giving, but I hope this 
isn't the kinds of optimisations you are doing at the Facebook. 
The problem isn't that the conversion is slow, the problem is 
that you are converting at all. Don't use text based formats for 
performance sensitive data!

Of course, maybe the 15% claim was pure exaggeration. I really 
hope that's the case.
