Re: Slow debugger loading

is the point of ZeroLink if it slows things down?


As it says in the ZeroLink documentation (http://developer.apple.com/documentation/DeveloperTools/Conceptual/XcodeUserGuide/Contents/Resources/en.lproj/05_08_bs_linking/chapter_35_section_10.html),  it speeds up the build/launch time in most applications by deferring much of the linking job to runtime, where it happens as needed.

Depending on the structure of your application and how much code it needs to load in order to get to the runloop, this can be a big win—or a big lose.  There are specific issues discussed in the documentation that take up a lot of time at launch.  Generally, if launch time under ZeroLink is prohibitively slow, then your launch time in the normal case is probably slower than it needs to be.

Your choices are to restructure your launch-time code loading to make ZeroLink useful and make your app faster for end users, or don't use ZeroLink.
