The HTTP Archive (<http://httparchive.org/>) audits the setup and performance of popular websites, reporting things like load times, download sizes, performance scores, waterfall charts, and cache headers. They provide per-site reports as well as aggregate data about trends in web technology. They added several Wikimedia wikis to their index last month and the first two reports (dated Oct 1 and Oct 15) are available. The reports for the desktop site of the English Wikipedia are available here: <http://httparchive.org/viewsite.php?pageid=11675485>. (I do not expect to see much variation across Wikimedia wikis, since they are co-hosted on the same infrastructure.) There's a wealth of data available. It should help us assess how we're doing relative to other sites and where we need to improve. I plan on studying this data on an ongoing basis and I invite / encourage you to do the same. Be sure to share your discoveries with this list. --- Ori Livneh ori(a)wikimedia.org
