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.
Not all back end code. Certain applications.
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.
Text representation has its own advantages.
