# A basic, synthetic benchmark of the impact HTTP client has
# on the speed of talking to ElasticSearch in the Tire gem.
#
# In general, Curb seems to be more then two times faster the RestClient, in some cases it's three
# to five times faster. I wonder if keep-alive has anything to do with it, but it probably does.
