The choice of feed parsing libraries in Ruby has been reasonably limited so far, so Feedzirra is a most welcome addition to the Ruby ecosystem. Its focus is on pure speed - it uses Nokogiri (an ultra fast Ruby XML parser that depends on libxml) and curb (bindings for libcurl - to do the HTTP work) so compilation is required. Feedzirra was designed to be used to fetch thousands of feeds, process updates quickly, save on bandwidth (with conditional GETs, etc) and be dead simple to use.
