[erlang-questions] Some notes on making a random erlang program (egitd) faster

[Alain O'Dea]

Hi Jay,

egitd was created by Tom Preston-Werner (@mojombo) for GitHub.  Andrew used
it as a project example for performance tuning.

Design considerations aside from performance weren't part of the primary
goal of Andrew's experiment.

You should fork Andrew's egitd and experiment with best practices
refactoring and write a blog article ;)

Cheers,
Alain
