# UPDATE: I benchmarked parsing JSON and it's way way faster. I'm going to transition to requesting
# JSON from flickr and store the cached data as JSON too.
#
# With Rreset (http://github.com/javan/rreset/tree/master), I am caching some of the XML 
# returned from Flickr API calls. Then, on subsequent hits, the cached XML is loaded and parsed
# using Hash.from_xml which is an implementation of XmlSimple. I was curious if it would be 
# faster to first convert the XML to Yaml and parse that on cached hits instead. Yaml was the 
# obvious winner. There are probably way faster XML parsing libraries out there, 
# but I wanted to stick with the Rails defaults.
