I don't believe the thrashing is abnormal and, while mildly
inconvenient, certainly doesn't warrant me investing the time into
profiling the issue.
I simply wanted to ask the xcode-users list in the hope that an
Xcode developer might popup up and say "yup, that's symbol indexing
and you can disable it by ...".
I still live in hope that an Apple employee might chime in...
It's most likely to be indexing. Without forensic evidence, we can't
really tell, but indexing is the most disk-intensive background task
done by Xcode. Dependency analysis is second, but it just stats the
files to check their mod dates, while indexing (obviously) reads the
fulltext of files.
As was mentioned, having indexing take a long time and a lot of disk
activity may be a side-effect of poor project configuration:
- Inadvertent or unnecessary inclusion of non-project files in the
project
- Setting the Project Root (Project > Edit Project Settings > General)
to an enclosing folder that encompasses a lot of non-project files
- Symlinks or other external references in your project files
There is no way to disable project indexing, as dozens of Xcode
features rely upon it.
