However, I don't imagine either will be used by Wikimedia, as they are written in Java, which is slow and takes up too much memory compared to natively running stuff (i.e. C or C++). It's already bad enough that we're using PHP! (In one extreme case, a diff took 45.5 seconds in PHP while the same algorithm took 0.5 seconds in C (or maybe C++) (this is from a developer)).
java cannot beat raw C-code (except sometimes) but it sure is an order of magnitude faster than PHP. a java VM does need a lot of memory to run fast, but you need that anyway if you want reasonable search performance.
this is from a developer, too ;)

P.S. mono is said to be quite slow up to now :/
