I've been wondering about the apparent increase in downtime since update_status started to be widespread: is there any way to check whether it is responsible for a significant part of the increased server load ?
The overwhelming majority of the d.o downtime has been from a slammed DB server. For the server side of update(_status?).module, the DB is only touched once every 6 hours to regenerate the .xml files for the release history for each project. These queries don't show up in the top N list of most expensive queries on the DB server. To actually serve the history, there's no Drupal bootstrap at all, just an ultra- thin PHP wrapper. So, to answer your question: "Yes, we checked. No, it's not responsible at all". Cheers, -Derek (dww)
