It's complex, in that it's very complete and very flexible. Sometimes 
too flexible. However in Ruby it's a lot nicer...it becomes a really 
easy GUI library to work with.

Yes.

Yes, and other than query differences you won't have to juggle native 
libraries in any way. And if you used something like ActiveRecord, you 
wouldn't have to juggle queries either in most cases.

Of course.

I love that this comes up as a concern. Ruby 1.9 has many specific 
optimizations where it's pretty fast (like integer math) and has other 
areas where performance has degraded (eval and string operations come to 
mind). I would recommend you benchmark whatever code you're looking to 
run on all impls before you make decisions about performance; you might 
be surprised. At any rate, the answer is yes, we'll start aiming at 
implementing the same optimizations in JRuby, probably after the 1.1 
final release.
