As a user, I can have better memory performance on Publish by using SAX instead of etree for comps and updateinfo XML production
Etree is currently used for the XML production of comps and updateinfo files at publish time. Etree supports great features, however it’s slow and eats lots of memory. A user, jluza has run into several memory issues which were caused by the use of etree. In a fork of Pulp he maintains, replacing the etree usage with XML resolved the memory issues and reduced the publish time.
