Yeah, LuaCocoa definitely needs a future release dedicated to
performance optimization. This is why I still call it a 0.1 release
instead of a 1.0 release.

I think most of the bottlenecks are related to parsing XML which I
suck at. (Lua spoiled me because I rarely actually needed to use XML.)
BridgeSupport metadata also contains references to "dependent"
frameworks which I am dutifully respecting which is why so many
frameworks get pulled in and processed. While these dependencies will
need to be respected, perhaps a future optimization could defer the
XML parsing to more lazy/on-demand if more efficient XML parsing
doesn't solve the problem.


Thanks,
Eric
