I have a project with a 50 source files and a few thousand lines of code.
When I want to debug the project it takes about 25 seconds for the
executable to launch.  I have a 1.5GHz Powerbook G4 with 1.5 GB ram.

This slow loading has been a problem for some time.  There was a time after
the release of Xcode 2.0 when it was fast but then for some reason it slowed
down.  I currently have MallocStackLogging defined but there was no
difference whether it was on or off.  This delay is quite annoying when I am
in a debug cycle.  

The strange part is that the CPU is not at 100% during this wait but there
is a large burst of disk activity at about 17MB/sec for about 10 seconds.
If I run Shark there is a lot of time spent in NSTableView drawRecta and 14%
of the time is spent in objc_msgSend_rtp.

Can anyone tell me if this is normal or if perhaps I have something setup
incorrectly?

Thanks.

Bruce
