Hello, I'm working on migration to HipHop at Wikia (we run on MediaWiki 1.16.2 with tons of our custom extensions and skins).
At this point I'm testing and benchmarking all different use cases and so far I didn't run into any serious problems - however there were memory corruptions when using DOMDocument (Preprocessor_DOM) under heavy load, but it is already fixed. Btw. I had to apply this patch http://pastebin.com/qJNcwp99 to MediaWiki code to make it work (commenting preg_replace is just temporary change). Very likely in our approach we will mostly target HipHop (not Zend) with future development, since we want to switch our developers to work with HipHop as well.
