I'm a bit surprised that your sample doesn't contain symbol information
- usually the sample reports and backtraces would show no, or very few,
numeric addresses. This makes it much more difficult for me to say if
it looks OK or not - the Xcode team would have to step in and take
over. A couple of comments (please take it with a grain of salt, given
my previous disclaimer):
* When I have performance problems in Xcode the sample report is
usually much, much, longer because the main thread is so often busy
with handling indexing (performed on a timer in the main thread) and
funneling status information from background threads (building, et.c.).
This doesn't seem to be the case in your sample - something that I
would have expected to be good for performance. <shrug>
* I don't recall seeing "XXXcharacterAtIndex:" methods in the sample
reports, while they seem to be the bulk of what's going on at your
site. It's probably significant, and characteristic for your problem -
but as it's not something that I've had problems with, I don't know
what to advice.
Still, whenever I have CPU bound performance problems in Xcode (or any
other app for that matter (including our own...)) I file a new case and
provide sample reports. I would encourage you to do the same! If you're
not 100% certain that the problem is with Xcode, or that it is CPU
bound, then a couple of snapshots of "top" running when you have these
problems would probably also be interesting (to look at memory
statistics, activities of other applications, et.c.).
