billdueber / ruby-marc-serialization-benchmarks.rb

Created September 28, 2010 17:29

	# Code to benchmark various serializations of MARC records using ruby-marc
	# Not included is XML -- serialization using ruby-marc is ridiculously slow and the # filesizes are bigger than anything else. Even with the lib-xml reader,
	# deserialization is also relatively slow
	#
	# I didn't bother to benchmark json/pure in later runs because it's just so damn
	# slow that it would never be a good choice.
	#
	# My results can be found at http://robotlibrarian.billdueber.com/sizespeed-of-various-marc-serializations-using-ruby-marc/
