## I18n backends benchmarks
#
# All these benchmarks were performed using REE with the suite at
# at http://github.com/svenfuchs/i18n/tree/master/benchmark/run.rb
#
# When compared to ActiveRecord backend, Redis and Tokyo
# just cannot store procs. All other tests pass.
#
# Used rufus-tokyo (1.0.7) and redis (2.0.0) as gems and N = 10.

# Rails developers have long had bad experiences with fixtures for
# several reasons, including misuse.
# 
# Misuse of fixtures is characterized by having a huge number of them, 
# requiring the developer to maintain a lot of data and creating dependencies

# of fixtures are only used by 20% of tests.

# An example of such tests is one assuring that a given SQL query with
# GROUP BY and ORDER BY conditions returns the correct result set. As expected,
