With Shark running a malloc trace, I'm not able to type that line
and delete it before the trace finishes. With a time profile, I
can barely finish deleting it before the profile finishes. (this
is on a PowerBook G4)
It seems that most people having trouble with Xcode 3 performance
are running single-processor systems. I've only used Xcode 3 on a
MacBook and an Aluminium iMac and have had absolutely no problems
with performance. The task above completes as quickly as it does in
any text editor.
For the sake of completeness, the performance problems I'm
encountering are a function of project/file size as well. A framework
I've been developing has a dozen .m files, and all but one are < 500
lines. Xcode 3 works great with that project. The specific file/
project I referred to in my bug report is
https://bibdesk.svn.sourceforge.net/svnroot/bibdesk/trunk/bibdesk/BibItem.m
which is significantly larger. Xcode 2.5 on my 8-year old Pismo has
the same or better editing performance.
Chris Espinosa mentioned that there could be issues on single
processor systems because the garbage collector thread has to run on
the same processor as the main thread - is there anyone here running
a dual (or more) processor system experiencing these performance
issues?
My dual G5 system is able to keep up with typing for the most part,
which is why I blamed the collector for my problems. Performance
still isn't as good as previous Xcode versions, though.
