I've seen this thread about slow DYLD times in the past and used it to debug our startup slowness but wasn't able to see any significant delays in the linking. I think it's worth doing some profiling of the app, checking not just the dyld load times but also our app code where things are slow. Things might have regressed since the last time I measured.
